I can totally feel your pain. I have horrible lower back pain and I wake up in the night with hip pain. I have had CD a long time and this flare is the first time I have had such horrible back pain. I am starting remicade soon, so hopefully a remission is in sight. As for vision problems, I have recently needed glasses due to my flare, I had Lasik 2 years ago. The joint and back pain is hard, but I am learning to deal with it. You are not alone. I take a couple tylenols, but if you have any suggestions, my ears are open. I hope this helps, even if it only gives you someone you can relate to.
