It was then that I researched the
side effects of my prescribed drugs and determined that I should stop taking the Singulair. My doctor prescribed a replacement for Singulair, and within a month the numbness went away.
Over the past few months I have tried to get back into running. I used to run frequently, always training for a 5k, 10k, or half-marathon, so not sprinting. I have never had a problem with my heart rate or my blood pressure, but now I do.
