A week ago while being a passenger on a car trip I developed a large sudden rash. First it appeared on the back of my left hand, I am right handed. Within five minutes my thighs and arms also broke out. Within a couple of days the rash went away on my legs, but it seems to be getting worse on my arms and now my feet. I will also have random blister breakouts that last about 24 hours. The rash has always been severely worse on the back of my left hand, almost a purple color with the most bumps. For the first two days the rash felt like a chemical burn, but since then has switched to severely itching. I am concerned because I originally self-diagnosed it as a heat rash, but I have never had one before so I wasn’t very sure. If it is a heat rash should it be getting better by now instead of still spreading? Also, why would it be the worst on the back of my hand? My chest, stomach, and back are all completely fine. If it was a contact allergy I feel like it would be getting better by now. I really have no clue what it would be. I haven’t changed soaps or detergents. I tried Benadryl and didn’t notice a difference, other than the usual sleepiness. I have prescription cortisone cream (I have a history of sensitive skin) and that does help, but I read you’re not supposed to use creams on a heat rash. I have been getting the most relief for my hand by soaking it in a salt water solution. Has anybody encountered anything like this before and/or does anybody have any suggestions to help control this thing?
It can be due to hives which are mostly due to allergic reaction. Take some antihistaminic like Benadryl or Claritin and apply some calamine lotion on the hives. If the symptoms persist then please get it examined from a dermatologist as you may need oral steroids which are available under prescription.
