I have been taking Tramadol for over a year now for chronic pain, I currently only take one 50mg pill a day, but I have noticed that within the past few months my hair is starting to thin pretty badly. I was put on Synthroid for my thyroid about two months ago, and currently take Humira for RA and Yaz as well. My hair seems to have gotten worse within the past month or so. Could this be from the length of time I have been on tramadol?
