I am a 40 y/o male, I went to the Dr. Monday the 22nd with these symptoms-
swollen fingers and knuckles, and severely (I really can't stress how bad this itch is) itching hands and fingers, and nothing OTC seemed to help. I tried Benedryl capsules, hydrocortisone cream, Benedryl cream, cold compress and soaks. After visiting with the Dr. he surmised that I had developed an allergic reaction to some shrimp I had eaten on Friday the 19th. He prescribed singular 10mg 1x daily, cimetidine 400mg 2x daily, and zyrtec 10mg 1x daily. The symptoms stopped almost immediately upon starting these meds.
Here's my problem, it's 3:40 AM on Saturday a week after eating the shrimp, the symptoms are back, and the script the Dr. gave me was for only 5 days. I have not eaten anymore seafood, and this itching in my hands is keeping me from sleeping.
My question is. If this was a reaction to shrimp eaten on 1/19/07 should the reaction still be present on 1/29/07? Also, is it safe to assume that since the prescribed meds seemed to alleviate the problem that it is indeed an allergic reaction to something?
My eating habits have not changed, I have tried nothing new. My environment has not changed either, no new soaps, detergents, etc.
Thoughts, suggestions? Any help would be deeply appreciated.
