You are saying to have taken antibiotic and diflucan
since 12/25 and steroid. The painful lumps that appeared in your right chest could be related to:
- infection of local lymph-nodes
- skin infection
most probably due to antibiotic intake.
I'd suggest to get checked by a physician/dermatologist
to determine the right diagnosis and if it might need surgical drainage.
