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?

  • I would get tested for Lyme disease. Esp if it can't be poison oak or ivy, since you were covered. The tick bite dosen't always leave a bullseye rash. My bite was right behind the knee and it turned purple with a huge welt. Many people are bitten and never know it. Good Luck & Best Wishes.
