Interstitial Cystitis
"I recently started this medication for my ic , the side effects startrd right away . Fatigue, headaches,  severe pain in my lower stomach almost like constipation pains sharp and intense  this would happen about 20-30 mins after taking the medication and the pain would last a few hours before easing up, just in time to take the next dose , pain behind my eyes and the hair on the top of my head stated to hurt ... i stopped taking the medication days later .. I plan on going back to the doctor to find something else."
