I take tramadol for pain in my neck and back. Since I started I have been constipated. Does tramadol cause this? I try to go without laxatives but when I get to the 6th day, I am so uncomfortable that I resort to the laxative. Is this safe for me to do? I have tried metamucil, fruit, stool softeners etc. Nothing works except enema's or stimulant laxatives.
