I am 47 years old and I started these pills 2 months ago to deal with bad headaches, Since I began taking them: my hands ache, my right foot is swollen, my knees hurt, I have to ice them at night so I can walk in the morning, I'm moody, I have diarrhea, god-forbid I have gas, I don't want to eat or I'll have to poop almost immediately sometimes before I'm finished with the meal I have to run to the bathroom, my sex drive is up but I'm scared to have sex in case of anything embarrassing in bed. I have hemorrhoids and because I have to go so often they won't go away. I HATE these pills.
