I'm afraid I have little useful to offer. The presentation does indeed sound atypical for erthromelalgia. This is in any case a very rare condtion with which I have no personal experience. Alos, the dermatologist has tried all the agents likely to help, and then some.
A trial of other antihistamines (cyproheptadine, Polaramine, hydroxyzine) might be considered. (A GP or skin doctor can prescribe these.) Aspirin has been used in erythromelalgia as well. Also, a visit to a neurologist sounds reasonable, and more likely to be productve than an allergy consultation.

Within 3 to 4 days my MOM had her hearing back. I don't remember what he gave her. I have been on and off dialysis for 17 years and I am very picky who I will have work on me. Sometimes it is worth driving an hour to someone who knows there stuff and is not prolonging your suffering just to make money off you. My advice is to SHOP AROUND and ask locals who are good Docs in the area. WORD OF MOUTH! Hope your Mom finds some relief soon..
I'm now thinking that the problem may be stress.
I didn't recognize that I was under so much stress initially. However, I've come to realize that this is as much stress as I've been under in sometime.
Does the stress angle make any sense?
LOL
