If you’ve recently had a P-Shot, it can be unsettling to notice a small lump afterward. Perhaps you catch yourself checking the area more than once while you wonder if that lump is normal or if it means something more serious.
A lump after a P-Shot is one of the most common concerns patients ask about during follow-up appointments, and in most cases, it’s a normal part of the healing process. Still, it helps to understand what’s happening so you can give yourself some peace of mind.
The P-Shot, short for Priapus Shot, uses platelet-rich plasma (PRP) derived from your own blood sample to naturally repair tissue, enhance circulation, and enhance sexual function. It has become a trusted solution for men seeking to restore confidence and improve erections.
Clinical data support its safety. In one study, men with vascular erectile dysfunction who received PRP injections reported improved function, with the percentage of men able to maintain erections long enough for intercourse rising from 20% before treatment to 26.7% after treatment. Importantly, no major side effects were noted during the study period, further proving the safety of the procedure.
So, what does this mean for you if you’ve noticed a lump after your treatment? Keep reading as we’ll explain why a lump can appear after the P-Shot, which side effects are normal, and what kind of P-Shot before and after results you can expect as your body heals.
A lump after a P-Shot is usually a short-term reaction to the injection process itself. When platelet-rich plasma (PRP) is delivered into the penile tissue, the area may respond with temporary swelling, mild tenderness, redness, or light bruising.
For some men, this reaction feels like a small lump under the skin. The good news is that these changes are temporary and typically resolve within 4 to 7 days as the area smooths out again or returns to normal.
Do note as well that since the P-Shot uses PRP from your own body, there’s no risk of rejection. The treatment simply reintroduces your natural growth factors to restore healthy function in the penis. This is one of the reasons why the P-Shot is considered both safe and effective for men struggling with sexual dysfunction or looking to boost sexual performance.
Just like with any male med spa procedure that involves an injection, the Priapus Shot can cause a few short-term changes as your body responds to the treatment. These P-Shot side effects are typically mild, temporary, and part of the normal healing process, so you need not worry. Most men are able to resume daily routines and normal activities almost immediately after the procedure.
Below are the most common side effects you might notice.
Because platelet-rich plasma is injected into deeper penile tissue, it’s very common to feel some swelling or firmness in the area. It generally improves within several days as the PRP is absorbed and your body begins the healing response.
A little redness or light bruising at the injection sites may appear in the first few days. This is a typical reaction to the small needles used during treatment, and it fades on its own without intervention.
The treated area may feel tender to the touch, or you may notice mild sensitivity during erections in the first week. This is just temporary and will ease as tissue recovery continues.
Platelet-rich plasma injections contain powerful growth factors that stimulate tissue repair and new blood vessel formation. This activity can trigger a small inflammatory response, which is part of your body’s natural healing cycle. While this may contribute to temporary warmth or firmness, it’s a reassuring sign that the PRP is actively working.
One of the most common questions patients ask is what kind of transformation they’ll see from a P-Shot before and after. While every man’s body responds differently, there are some patterns we see consistently among our patients.
Men considering the P-Shot often share similar concerns:
Some patients seek the treatment as an option for erectile dysfunction related to circulation, while others simply want to enhance function and overall sexual wellness.
Right after the PRP shot, the penis may feel slightly fuller or more sensitive. This is mostly the body’s initial response to platelet-rich plasma and should not be mistaken for the final result. Mild swelling, redness, or firmness can appear, which usually settles within several days.
Noticeable changes typically develop over the course of 2 to 6 weeks. As the PRP stimulates tissue repair, new blood vessel growth, and increased circulation, many men begin to experience:
Some adult males notice a fuller appearance during the first week, with additional improvements becoming more noticeable after multiple treatments. In certain cases, increases in length and girth have been reported around the third treatment, though these changes differ from person to person and should be approached with realistic expectations, as they are best viewed as a possible bonus rather than the primary outcome.
The full effects of the P-Shot often build over a few months, especially with a series of 4 to 6 treatments, which is considered a typical course. By the end of treatment, some men notice sustained improvements for 18 to 24 months before considering maintenance.
While a lump after your P-Shot is usually part of the body’s normal healing response, what you do in the first few days after treatment can influence how quickly that lump, swelling, or firmness settles. Avoiding certain activities helps minimize irritation and gives the platelet-rich plasma its best chance to work.
Engaging in sexual intercourse immediately after the injection can aggravate swelling and slow down recovery. We recommend waiting a few days so the tissue can heal and the PRP can integrate without added pressure or friction.
Workouts that raise blood pressure or involve heavy lifting can increase blood flow to the injection site, which may make swelling or lumps more noticeable. Gentle activity is fine, but hold off on anything intense until your provider clears you.
Both alcohol and smoking reduce circulation and can interfere with the healing process. Since the P-Shot works by stimulating blood vessel growth, avoiding these habits, at least during recovery, can help the side effects smooth out quickly.
Blood thinners and NSAIDs (like ibuprofen or aspirin) can worsen bruising or swelling. If you’re on these, ask your provider about timing or safe alternatives around the procedure.
A small lump or firmness is normal, but if it worsens, lasts longer than expected, or is paired with significant pain, it’s best to check in with your provider to rule out other concerns.
Noticing a lump after a P-Shot is usually part of the body’s natural healing process. In most cases, it’s the result of temporary swelling or firmness at the injection site. These changes typically smooth out on their own within a few days as your body settles.
Since the P-Shot is made from your body’s own platelets, it works naturally with your system and is generally well-tolerated. Most men go on to notice stronger erections, improved sensitivity, and better sexual experience in the weeks following treatment. However, if a lump still feels unusually firm, causes painful erections, or lasts longer than expected, it’s always best to reach out to your provider for guidance.

After the P-Shot, you may notice slight swelling, tenderness, or firmness. Improvements in erections, sensitivity, and sexual health typically appear over 2 to 6 weeks. Full results can take several months, especially if you undergo a series of treatments.
A lump can form due to localized swelling, temporary tissue firmness, or the body’s natural response to the PRP injection. It’s generally a normal part of recovery and should subside within a few days.
You must seek medical advice if the lump is unusually firm, painful, increases in size, or lasts longer than expected. Your healthcare provider can assess whether further evaluation is needed.
Understanding that lumps are often a normal, short-term side effect may help ease your anxiety. If you’re still worried, you can continue to monitor the area, follow the post-procedure care instructions, and keep in touch with your provider for more peace of mind.
