There is a FB group for Ocrevus users that I've started checking out. There are frequent complaints of back pain, especially lower back. This could certainly be related to our reduced mobility or gait but there were just so many mentions of it I put it out to the group and someone posted that it is a known side effect. I couldn't find it directly on the Ocrevus site nor has it been mentioned by my Neuro but on the RxList.com site it is listed as an issue for 6% of people on Ocrevus. How about others here? I have always had a stellar back (once even admired by a Chiro ;-0 ) but admittedly my foot drop and reduced mobility could contribute to the lower back pain I'm experiencing. Then again I don't remember this pain a year ago...before I started taking it. Anyone else? https://www.rxlist.com/ocrevus-drug.htm#indications
