My arms, legs, wrists and everything hurts. I have tried cutting the 25mg of hydrochlorothiazide in half and I have taken that for about 3months and I am still having horrific pain. I stopped taking it for two days and I am not feeling as much pain. I also always had fairly decent fingernails. Now my nails seem to be splitting and peeling terribly. I thought it was the cold weather so I use moisturizer constantly but that doesn't seem to help.
