Hi my husband is heavy set, he get these large lumps under the skin of his inner upper thigh, groin area like 2 times a month. They are painful and they swell up even larger and get very dark red.. He has tryed to squeeze them and sometimes they burst out, with blood mostly. Why do they keep coming back? He has to cover them with patch bandaids so they wont hurt so bad.They usually take about 4 days to stop hurting and flatten out.  Any answers?
Welcome to Chat Doctor. 1. It seems like an infective cause with collection and pain.2. In this case if you are my patient I would have examined and send for an ultrasound scan done - which will help to evaluate the nature of the lesion and its content and extensions.3. After that depending on finding and amount of collection treatment will be a small incision followed by an antibiotic treatment.4. As a remedy keep area hygiene, do not disturb the area, no scratching or pressing the lump as that way it will complicate.5. Clean with antiseptic liquid, use soft cloth to avoid irritation to the area. Good luck. Hope I have answered your query.Anything to ask do not hesitate. Thank you.
