What Causes Red And Painful Rash In Between Buttocks?

I get a rash that is inbetween my buttocks, right down the crack. It is painful,

red, and seeps. At the same time this happens I get what appear to be acne on my

face and neck but there isn’t white stuff that comes out, just clear liquid, and

if they are disturbed they take longer than any sore I get to heal. I at times

also get them on my hands, but these are like little blisters. Plus I can get

what appears to be a boil that will get big then ooze out clear liquid right at

the top of the buttocks crack, and then bleed and then take weeks to heal. I

have had this for years, and ever time I get a new doctor they run a herpes

test, every time it comes back negative. I tried all sorts of creams, from

cortosol, to fungal to preparation H to soaking in bath with Epsom salts. The

only thing that seems to help is baby powder, but I have to constantly clean,

because if it does not stay completely dry then it just continues, even with it

dry it can take up to a few weeks to have it go away. This has been going on for

about 20 years. I was in the military and went overseas (Panama and Saudi

Arabia) and it occurred the first time in Panama and I was given something from

the doctor to put into a bath for me, but he didn’t have a clue what it was.I was prescribed an antibiotic and it seemed to lessen the time that it took to heal, but that stopped working and I was given a stronger antibiotic. None of the VA doctors that I have seen have any clue to what it is and usually I have to start the whole process of elimination over when my doctors change (which is a constant) and they start out with the herpies test, then move on to mites, even though in my records I have been tested for them and not once did it come back positive.
