Sounds abit like cholinergic urticaria, unfortunatly there is no magical cure and different things work for different people. This may also be an allrgy connected with food or latex (especially if your working in a kitchen). You could try an over the counter antihistimine such as xyzal (perscription only in some parts of the world) you can actually take over the reccomended dose on these antihistimines (dont go mad with them! But take maybe 2 instead of 1).
Also try taking vitamin b suppliment, suprisingly this seems to really help with alot of people I have spoken to.

Other than that try to see a dermatoligist to discuss further treatment.

Yea, it sounds like you have cholinergic urticaria. I have had this for about 7 months now and I have tried basically everything. No anti-histamines work at all for me...I have tried benadryl, claritin as well as other treatments I read about online. For a while, I was on doxepin which slightly reduces the problem, but it leaves you very tired all day. I also tried acupuncture which surprisingly worked for about 2 weeks and then it came back even worse. I am currently using a combination of two medicines and it has worked extremely well. I recomend this to everyone suffering from cholinergic urticaria. I take one tagamet (cimetidine) 400mg pill every morning and one at night. I combine night-time tagamet pill with one .5mg cogentin (benztropine) pill. Cogentin is used for parkinsons (i think) but it is an anti-cholinergic. I honestly have not had a single hive for 4 months. I don't guaruntee that it will work for everyone, but it sure works for me. Good luck!
