<s>[INST] I have a spot near my shoulder blade that is a raised, fluid filled white bump, surrounded by a red circle. It appears to have a small black dot in the center. It is painful to the touch. The bump has been there for almost a year, and was not painful, large, fluid filled, or discolored until a few days ago [/INST] Hi,This is possibly a sebaceous cyst that has become infected. I suggest you see your doctor as you may benefit from antibiotics. Regards,Dr K A Pottjnger,MBChB. FRCA </s>
