Anyone on tysabri and experience pelvic pain getting worse after each infusion? I will say I do have endometriosis and adenomoysis so my pain is flared often but every time after the infusions it flares badly for 2-3 days like clockwork and I don’t know how to stop it and my neuro isn’t sure and advise we could change treatments but my scans are stable so I’m not keen to go off tysabri at this point.
