Do I Have Dh?

I have had an itchy rash on my legs, elbow, and buttocks for a long time now. They look like little red dots that I scratch until they bleed, then they scab and itch some more. One dr thought it was scabies, but my dermatologist thinks it's eczema with really dry skin. Another dr said it looked like an autoimmune thing. The derm said she couldn't do a biopsy because I had scratched them so much that there was nothing to scrape plus I scratched to infection.

I have other possible celiac symptoms (GI) but no diagnosis yet.

Could this be DH?

Thanks.

Laurel

The only way to know is to have the skin around the rash biopsied. May want to find a new dermatologist if your doctor isn't familiar with how to biopsy for DH.

Yep, but if you have DH it can be painful, just to warn you!

Go to the drug store and buy a small bottle of iodine tincture (you'll find it in the first aid section in a brown bottle). Soak the pad of a band-aid with the iodine and put it on your skin. Wait for a few hours, up to 12, if you can stand it. If you don't have DH, you'll see a nice brown patch on your skin which will fade in a few days. If you have DH, you'll either start blistering under the band-aid or it'll itch and the entire area will be one large blister (which happened to me). Cheap and itchy, but a lot less $$ than a biopsy. :) happygirl, my biopsy came back negative (three different areas, around and on lesions), but the iodine test was a raging positive. That's how they used to do it before fluorescence microscopy of skin samples.

I'm confused...wouldn't the same reaction happen if you had any type of contact dermatitis? Why would this be specific for DH?

I did the iodine test last night. Shortly after I put the bandaid on, the skin next to the bandaid got goosebumps and became very itchy and looked like the rest of my rash. When i took the bandaid off this morning, all that was under the bandaid was a yellowish spot - no blisters.

I have been g.f. for a week now and the other rash I had is getting better, as well as the acne on my face has cleared up. I also have more energy and feel better. Still waiting for the blood test results, though.

I'm so confused! :wacko:

      Bread has about 8 g of protein per 100 g, so a piece of bread weighing 125 mg contains 10 mg of gluten. Bread has a density of about 0.25 g/ml, so 0.5 ml of bread contains 10 mg of gluten - i.e. a bread ball 1 cm in diameter. I think it would be unlikely to ingest this much from throwing bread out for the birds.

      Sciatica came to mind for me as well. You might want to get some imaging done on your C-spine.

      Maybe this is sciatica? When mine acts up a little, I switch my wallet from one back pocket to the other. this isn't a substitute for more serious medical help, but for me it's a bandaid.

      Terrible Neurological Symptoms

      OK so I just learned something completely new about this for the first time in years, that is REALLY WEIRD. One of my nerves that likes to "burn" or whatever is doing it every time I bow my head! I mean it is completely repeatable. Literally every time. Once my head goes beyond a certain angle *boom*. Nerve goes mental (lower right leg pain). What the...

One of my nerves that likes to "burn" or whatever is doing it every time I bow my head! I mean it is completely repeatable. Literally every time. Once my head goes beyond a certain angle *boom*. Nerve goes mental (lower right leg pain). What the hell. I've never seen a direct trigger such as this before that I can recall. The pain was the usual type I get from this problem - I suspect somehow the head movement was interrupting descending inhibition processes, causing the pain to leak through somehow.

      Zaalouk moroccan eggplant salad

      By Aretaeus Cappadocia · Posted

      I've only made this a couple of times but it's really easy and I love the flavor. If you can, use all of the ingredients to get the full palette of flavors. I use fresh or canned tomatoes and I don't worry about peeling them. If you don't have harissa, there are replacement recipes online. If you don't have the greens, I suggest adding a little chopped baby spinach or celery leaves to add a dash of green color to this red dish. Best eaten in first couple days because flavor tends to fade. Leftovers are still good, but not as vibrant. Ingredients 2 medium eggplants, partially peeled and cut into cubes (original recipe says 1 in, but I prefer 1/2 to 3/4 in) 2 tomatoes, peeled and crushed 4 garlic cloves, finely chopped or minced 1 tablespoon fresh flat-leaf parsley, chopped 1 tablespoon fresh cilantro, chopped ¼ cup extra virgin olive oil 2 tablespoons spicy harissa (I use Mina brand) 1 teaspoon cumin 1 teaspoon paprika ½ teaspoon black pepper 1 tablespoon apple cider vinegar or lemon juice 1 tablespoon tomato paste (optional) Salt to taste Preparation     • Heat olive oil in skillet or pot over medium heat. Add all ingredients and cook for 10 minutes, stirring occasionally. Cover and cook on low heat for an additional 20 minutes, stirring occasionally.       • Serve warm or cold as a side or with bread for dipping. Enjoy!
