Hi there. This looks like an injection site abscess or cyst following intramuscular injections. You need to consult a general surgeon to assess this lesion, he would decide whether it requires incison and drainage( abscess) or enucleation of the cyst. It could also be fibrosis of a portion of the muscle due to the drug injected. Hope this helps .Take care.
