For nearly 20 years I have been plagued with a itchy, blistery red rash that only?

Question

The first time I experienced this rash, it was on my buttocks, & spread to cover an area about 8 inches across. The eruptions since that time can be as small as a single blister, about the size of the ball-point end of a pen, or they can be dozens of blisters. If more than one blister is present, they are clusters, not stripes of blisters (I have experienced poison ivy before also) It usually begins erupting around mid May or early-June, and continues for 5 months. The individual blisters take about 5 weeks to go away, but the area will remain red & flaky for another month or so.
I have tried various topical treatments, including calamine, benedryl lotion, cortisone creams (OTC & prescription strength) and triamcinolone creams. I have also taken a number of oral medications, including benadryl, claratin, cimetidine, atarax and others. Nothing has provided anything more than a minimal reduction in itchiness, nothing seems to speed the healing of the rash.
Every doctor th

that I have checked with says that it's poison ivy, even when there is 0% chance that I came in contact with any of the oils. And, while I generally trust physicians, I don’t think that they believe the longevity, consistency, the eruption patterns of this problem or of my own diligence in avoiding poisonous plant contact. Last year I even went to the extreme of replacing everything that has ever been taken camping by my family, including the car-carrier. We do not have pets to transfer oils, and this year I have not gone anywhere wilder than my front porch. And yet, the rash has returned again.

It ONLY erupts on my knuckles, wrists, and knees since that first time.

I've done the food diary, and there's nothing in common...was on a vegan diet one year, and a high protein diet another year...been through detox diets several times. I doubt it's an STD, it started 2 years before my first sexual encounter, and the doctors haven't referred me to specialists or done any testing. It doesn't look like anything in ANY of the med books...(and I do have access to professional resources too...)

There is no pattern to suggest any contact dermatitis...and there's nothing that I only use in the summer/early fall & never touch the rest of the year. impetigo & other suggestions have many symptoms that I don't have.

Answer 1

Test for pollen allergies or any think that may grow up on the area that you ar,including oil or other natural resources into the ground.
It happen in a Summer time when you Ar more exposed.Or you gets can't stand the hit

Answer 2

Maby a food alergy. Something as simple a a preservative or additive in your foods that are unavoidable. Have you ever been treated for Mites or Scabies, perhaps herpies. I think many people get these kind of out breaks and there is no cure or remedy. Just keep a good personal hygiene and use lotion many health problems we face today seem to be hereditary that may even skip a generation or so, so you may not know if your Great Grandfather or his Grandfather suffered from these same outbreaks. As difficult as it may be to deal with it that may be your only option.

Answer 3

at first it sounded like shingles but then toward the end it started sounding more like eczema. also there are some STD's that might cause that and last so many years. would be a good idea to get allergy tested too.

have you been tested for psoriasis, dermatomyositis, herpes, and impetigo?

Answer 4

It sounds like eczema to me, do you have an allergy to latex?? I was using latex gloves at work and it got so my hands were a bloody mess, it was allergy related. Also psoriasis has a pus filled type that happens on the hands and feet. metabethazone works best on that.
