I have an inflamed cyst on my left shoulder. It is small and is in the sebum gland. I was given augmentin, evion forte, chymoral forte, sompraz d and fucidin ointment medications but the cyst isn't getting smaller. Further I got a yeast infection with increased use to antibiotics. I'm applying candid ointment and stopped antibiotics. The itching has subsided for now but it still pains. Please recommend a medicine for this. Please advise me if I have to go for surgery. How much does it cost and recovery period for this? Will there be stitches involved?
