Have an oval lump under top crease of buttock on left side...seen the doctor and he gave me antibiotics for ten days should I be concerned....have seen articles of a cyst...had a cyst same spot about 25 years ago that I had to have cut opened and packed with gauze....
Hi, If the lump size is small (less than 1 to 1.5 cm), it could possibly be an abscess especially as it is present in the crease of buttock, a common area for infection. The area is wet commonly and in summer, the more and so infection is common. You must have had the same lesion, long time ago and if this does not rupture on its own, similar treatment might be necessary after 10 days. Antibiotics will help in reducing the infection size and also stops it from further spreading. If it is paining, you can take a painkiller NSAIDs like diclofenac or diclofenac. I think it is nothing to be concerned about. Take care. Hope I was helpful. Any further queries, happy to help.
