Hi, I am 45yo male that up until I turned 40 was healthy, fit, and in good shape. Last year I noticed my prostate was enlarging and also having trouble in my colon/ intestines. follow up included removing a polyop from me and prostate checked out ok(no growths), normal aging.
Ok I think I'm back to normal. But about 2 months ago I felt a lump on the back of my head. had my wife look at it, she thought might be something under my skin causing infection. So we went ahead and opened it up, lots of puss came out, almost no blood though.
Anyway after a few days noticed it had formed a thick scab, about the size and thickness of two pennys stacked together. I noticed it when combing my hair and catching it with comb. Opened it up again added my triple antibiotic and after a week passed, I now have 8 of these puss filled bumps all over the back of my head, they all form scabs, but have not seen any blood at all. Now into my second week, no improvement, however I am now feeling extreme muscle and joint pain and stiffness in my neck, shoulders, chest and arms, its getting to a point where I almost cant move, My legs are weak and I must use my arms to help pull myself up to a standing position. today I noticed that my feet and ankles are swollen( I have never had swollen feet ever). also feels like I got a bad muscle cramp in my right calf, muscle is very tight, and I must stretch it out each time I go to stand and walk.
A couple days back I went all day feeling like my ears were plugged, occational ringing, then the following morning, woke up and opened my eyes and everything was spinning, managed to stand and that made it worse, sat down for 5 min and then went for the trash can to throw up.
I went back to bed and slept another 6 hrs, woke up feeling so weak.
On top of all this, I got hemoroids, never had them before either. One last thing, the skin on my entire body will break out in thousands of red bumps, like a rash or something. it comes and goes and remains mainly under clothed parts of my body. My forearms, face,etc. doesnt seem to break out.
All this has happened and is still present today. All within the last 3 to 4 weeks.
Has anyone ever seen so may things go wrong in such a short amount of time? will I be in a coma next week? Is this one problem causing all these symptoms, or do I have mutiple things at work here?
Love to get some feedback, and yes the clinic is on my priority list of things to do.
