[queenb7887]

my husband has had a quarter size boil of some sort on his left shoulder. it has been there for about a year n a half now. it looks like it is filled w fluid and blood. sometimes it gets red and hard, other times it is jelly like. it also get a green ring around it every so often. these last two days his whole left arm has been hurting and sore. what could it be and what should we do.

Hi
Welcome to the MedHelp forum!
This 'lump' can be a boil or hair follicle infection, an abscess, an infected cyst or a tubercular cyst. It is difficult to diagnose on net. Generally a fine needle aspiration cytology is done to find the cause. Otherwise some doctors do a CT scan. At times clinical examination results in diagnosis. Treatment will depend on diagnosis can can vary from medication, incision and drainage to excision. Please consult your PCP for primary examination followed by proper referral.
Take care!

it possibly could  be a cyst or it could be something more serious best thing to do is go to a dermatologist and have it checked out

I had one of those on my chest, like jefelex said, I went to the doctor, he cut it open with a scalpel, drained it for a week and it was fine... hurt like hell when he cut it and squeezed on it to get the infection out but it was fine after that! Good luck!

I had one of those not even 2 weeks ago, for about 2 years, and it was fine until about a month ago!  I went to the doctor who cut a hole in it with a scalpel - it pussed for about a week or a little more, and now it is gone.

The pain will be gone within a day, and a lot of puss will come out - but they are no big deal once they have drained

Good luck!
