Can YAZ grounds dark sweats?
Answers: Sweating is one of the serious side effects of Yaz. Stop using it, and telephone your doctor at once.
It *might* be the cause, but hours of darkness sweats are a VERY SERIOUS symptom of several potential diseases (or may mean nil at all). You MUST go to your doctor and recount them that you're having hours of darkness sweats! possibly -ask the gyn.
I used Yaz. I never experienced that but I did have intense stomach pains which my OB and my prim support provider denied were cause by the pill. Imagine an ulcer but 10 times worse. My pains stopped days after discontinuing the pill. I would google Yaz and Side Effects to see, that's what I did and found that stomach backache is a possible side effect. I would ask your doctor and if he/she says no dawdle a little while longer and see. If it continues, I would ask for a different pill.
