Minutes exercise symptoms and conditions

oh yea...i forgot to mention dry eyes and a hacking cough that was severe but has since gone away, really bad pain in legs, elbows and joints and toes that feel broken to the point that i recently had to get on pain meds, over counter meds didn't do the job. the more i read about lisinopril the more i'm convinced to start a half dose tonight. i'm going to experiment by tapering myself off and if i live through it i'll let you all know if the side effects leave.
