When I have an ejaculation my sinuses get stopped up. When I take Viagra my sinuses get stopped up as soon the drug takes effect. It lasts between a half hour and an hour. Using my CPAPE machine seems to relieve the condition.
I've read about how Viagra works but am unable to determine from the material how PDE or Nitric oxide or whatever makes it affect my sinuses and I would like to know. None of my doctors can or care to answer this question. Curious minds want to know.View Thread
