You should seek medical evaluation promptly rather than self-treating. Developing a fever, worsening pain, and swelling five days after an intramuscular injection of hormones strongly suggests a localised infection, such as an abscess or cellulitis. Self-administering co-amoxiclav or applying heparin ointment is not safe; it may not target the specific bacteria involved, could lead to complications, and might delay necessary treatment. A healthcare professional needs to examine your thigh to determine if you require targeted prescription antibiotics or if the area needs to be safely drained. Please visit an urgent care clinic or your doctor soon for proper, safe care.

Since your physical tests are normal, your symptoms are likely driven by performance anxiety. High anxiety releases adrenaline, which constricts blood vessels and can override medications like tadalafil and testosterone therapy. To help your treatments work effectively, the key is reducing pressure. Shift your focus from performance to connection and mutual touch. Open communication with your partner can relieve immense pressure. Practice deep breathing techniques to calm your nervous system. Finally, consult your doctor to review your drug regimen, as high-dose tadalafil and testosterone need careful supervision. You are physically healthy, and as anxiety decreases, your body will respond naturally.

It is relatively common to experience mild pain, redness, or a low-grade fever after your first testosterone injection. This is often just your body adapting to the oil-based formulation. To manage this, apply a cold compress to the injection site for 10-15 minutes and consider over-the-counter pain relievers like paracetamol for the fever and discomfort. While local irritation is normal, if your fever worsens or if the injection site becomes increasingly hot, swollen, or leaks pus, contact your doctor to rule out an infection. Otherwise, these mild symptoms should improve within a few days.
