8 weeks, but have had problems on and off for years. This was the longest spell that I couldn't seem to heal from. Dr. said it was chronic. I am 11 days out from my LIS and feeling great. Now I am obsessed with my Bm's each day. I need to ensure my diet is good....got a high fiber cereral and try to eat more fruit and veggies. I take Metamucil and stool softeners. I am so relieved...I just NEVER want to have that pain in the a&& again!
