<s>[INST] Hi doctor,I had a small growth like in my thigh near anal part.  It was first observed in year 2010 and was slightly increasing its size very slowly.  But it was soft in nature.  Now it is about 1.8 cms in diameter. Today suddenly I felt that it became slightly harder as if it is pressure filled.  I have Piles.  But no treatment has been taken till now.  Is it dangerous that tonight itself should I visit the hospital.  Advise please.  I have high blood pressure also normally. [/INST] Hi.This looks to be a prolapsed pile which has gone into thrombosis. No need to worry. Take some pain killers. Have sitz bath in a warm water. It is a good idea to visit a hospital to see the blood pressure.If you have a history of high blood pressure you have to take a regular treatment under the care of a Physician so that if the surgery is required you can be for for surgery. Also you will be checked to see the lump and confirm a diagnosis. </s>
