bumps on arm/groin area

[antkurl113]

hello i am just curious i have had a few bumps on my under forearm. they have been there for maybe a year and have never given me any trouble. they dont itch or hurt or anything. they are sort of spread out and theres around 8 of them (3 distinct bumps and 5 smaller ones). they are no bigger then a small pimple, but they dont pop. there around  5 of the same pimple on my inner right thy by my groin area. just recently a new bump appeared on my lower right forearm where the other bumps are located. this bump is quite larger and resembles a pimple but has a red rash like ring around it around 2 inches wide. i poped this one a day ago and alot of pus came out. now a day later after i bugged it pretty much the whole day it is more red and has the ring around it. please help me out i am very worried about what these bumps are.

Hello,

Thanks for writing in this forum.

Without examination,confirmation of a diagnosis is tough but it sounds like sebaceous cysts. They are swollen, blocked grease glands that look like yellowish pimples. They occur  in dozens or more. If they become infected, they can be treated with antibiotics or excision and drainage.
Second possibility is of a lipoma which is a benign fatty tumor. Third possibility is of enlarged lymph nodes that can cause a lump. Swollen lymph node is usually caused by a viral or bacterial infection.
I feel that you should consult a dermatologist and get it evaluated.Biopsy may be needed to make a confirmatory diagnosis. Treatment will involve excision of the lump in most of the above cases.

Hope it helps.Take care and pls do keep me posted if you have any additional queries.
and on how you are doing.
