Can anyone give me some advice please? I have developed a lump which is similar to a blocked hair follicle but larger at the top of the leg just past where it meets the body. I am type 2 diabetic but am being reassed as my Metformin was making me ill - weakness and no strength - so have not been taking anything. I have been monitoring my blood and highest reading in morning before food was 8.2. this morning I have been given antibiotics from the doctor and told if the lump grows or hasn't gone in the next 2 weeks to go back to see her. Am I overreacting - she didn't seem overly concerned - the lump is quite large - but just said if it doesn't go I may need a biopsy or it may have to be lanced. Has anyone had something similar that responded well to penicillin? Any help will be greatly appreciated.
