If I am extremely allergic to sulfa. My well water has sulfur in it. Could this be causing me to break out in a rash?

My doctor believes me to be allergic to sulfa as every medication that I have had with sulfa I end up in hives. I was just talking with my sister and we think that the sulfur in the well water has also affected me. Symptoms that I have had that I feel could be linked: headache, fatigue (extreme sometimes), muscle aches, rashes including yeast infection on my foot, thumb and mouth at times, and blemishes. I did one time live in an area where I had city water... I had energy and a clear complexion and never any of the symptoms above. I live back in rural well area and suffer with these all the time. This was recently discovered and have to had a chance to speak to the doctor. I don't even drink the water. I just use it to cook and shower. I buy bottled water that's been filtered.
