Wave/flashes of intense itching all over
Last Thursday & again last night I woke up about 2-3am with intense itchiness on my hands which rapidly spread to my feet, then the rest of my body and finally my scalp & ears. I was covered in tiny red bumps in minutes. It was so itchy it crossed over to a painful burning sensation. The first time it also was followed by a sensation of swallowing something too big, although I was not actually swallowing at all. Last night I took two benedryl as soon as it started for fear it would effect my throat & breathing, & didn't have that part. In both cases the itchiness & bumps did not last more than an hour.
The only thing I can think of is that I ocassionally take Diclofenac (an anti-inflammatory) for my arthritis-like symptoms, and on both these nights I did take it at about 7-8pm. However, I have been taking it for over a year & have never had any problem before. Could an allergy like this just pop up out of no where & isn't it especially strange that it comes & goes so fast? Could it be I've become allergic to the time release portion of the medication?
