Contact your Gp or maybe some one else with experience in your chosen profession who works with that chemical.. you wont be the first to have a reaction to it and someone might have a good little tip to help you get sorted. all chems have a side effect and its just a matter of finding out if you can stop your reaction, eg is it irritating the skin then use a barrier cream?
Edit would a face mask be out of the question ?? eg is it the fumes you react to
Sounds like maybe an allergy. You should quite med school now and go into something without chemicals (well at least not the same chemicals) like law.
