What could a blister like hard lump on buttocks indicate?
Patient: Hi, this is quite embarrassing but i have a swollen bump on my butt. it's really hard all around the outter part and then has a blister like center. I had one before on my leg and when i went to the hospital they said it was a spider bite. this was a year ago. what would it be? Doctor: Hello!Thank you for the query.It is really hard to give precise answer not being able to see it. Hard lump usually indicates some inflammation. If there is a redness and pain in the lump area, some small abscess can be the reason.If it is only hard, but painless, it may be allergic reaction to some bite indeed.The best way is to consult dermatologist or surgeon with this lump. If it is an abscess, you should have it incised and drained. As it is similar to the lump you have had before, swab test of it should be also done.Hope this will help.Regards.
