Hello,
Based on your symptoms and the photographs, the bumps appear to be inflamed subcutaneous nodules at previous injection sites.
Possible causes include:
Injection-site inflammatory reaction: Localised swelling caused by irritation or inflammation.
Injection-site granuloma: A persistent inflammatory lump that can develop after injections.
Localised infection or abscess: Particularly important to exclude because the bumps have enlarged and become tender.
Fat necrosis or local tissue changes: These can occasionally develop following repeated injections.
The photographs show raised, discoloured swellings, but it is not possible to determine whether they contain fluid or represent solid inflammatory tissue from images alone.
Since one lump is enlarging and painful, an in-person examination is important.
Next Steps
Consult a general surgeon or dermatologist, particularly because the swelling has increased in size. A soft-tissue ultrasound may help distinguish an inflammatory nodule from a fluid-filled abscess. If an abscess is confirmed, drainage may be necessary, with antibiotics depending on the examination findings. Avoid injecting into the affected areas. If the peptides are unapproved or self-administered, discontinue their use pending medical evaluation. Inform your doctor about the exact peptide, dose, injection frequency, and date of your last injection. If symptoms persist or the lumps recur, further evaluation for an injection-site granuloma or atypical infection may be required.
Health Tips
Do not squeeze, massage, puncture, or attempt to drain the lumps yourself. Keep the skin clean and avoid applying steroid creams or antibiotics without medical advice. Seek medical attention if you develop fever, spreading redness, increasing pain, pus discharge, or rapidly enlarging swelling. My recommendation: The photographs suggest localised injection-site inflammation, but an abscess needs to be excluded because the lumps are tender and enlarging. A clinical examination, potentially supported by ultrasound, is the safest next step. Wishing you a speedy recovery!
