Hi, Recently I noticed I had an itch with a small bump on my left buttocks, it appearing to be caused by an insect bite. I scratched it and it had swollen. The next day I noticed it was sore to sit down even on cushioned seats. The lump is now harder almost like a hard cyst about the size of a grape. It does not itch anymore but it s really sore. I almost thought it might have been a pimple and I tried to pop it. I realize trying to squeeze it may have caused more swelling, however the grape like hard cyst still remains. This has been going on for about 4-5 days now and I m thinking I should see a doctor. If it was an insect bite my guess would be mosquito or spider. Please advice on if I should seek further medical assistance, because if i don t, it will save me a lot of time and money. Thanks
