This all started about 4 months ago, I woke up one morning and couldn't lift my shoulder, it felt honestly like it had been ripped out of socket, but I was never injured there previously. I went to the chiropractor and he gave me an adjustment... the shoulder pain went away, however, since then I have had chronic constipation, and my BMs are sometimes less than once a week. Before the adjustment it was twice a day. Whenever I do have the urge to go, I literally have to cross my legs or contort my body to even release the smallest amount of feces. I strain and strain, but nothing happens. I can't even feel it most of the time, and I never have pain in my lower abdomen, like you would normally if you were constipated. I've tried laxatives, to no avail, also once I went to the Emergency Room and the attending recommended Fleets Phosphosoda, and that didn't work either. I'm starting to worry about colon issues, and thinking there is some sort of blockage or a tumor or something. I read something about anismus, the pelvic floor being damaged, but honestly I don't understand most of it. I need a little guidance here, starting to freak out. PLEASE HELP!
