I am recovering from a severe blistering rash which covered the back of one leg and parts of the other thigh. I thought it was poison oak but although I was hiking, I wear long pants and have had no direct exposure that I know of. I also started recently on Chlorthalidone. Is such a severe rash a possible reaction to this drug? Is it possible to react to poison oak even if wearing long pants and sleeves?
