I looked into red light therapy and it seemed promising to try to reduce inflammation and joint aches, so I was prepared to pay for the best red light setup I could afford. My doctor is open to things that work and cause no harm, but she gave me a big NO to red light therapy while taking prednisolone. The combination is apparently not good. It's one of the things I'll be looking at again once the prednisolone is finished. In the meantime, we can all get natural red light exposure from morning light. The more time outside in morning light each day, the better.
