Hi. Hope this is a good day for all. I was wondering...does anyone know if low blood pressure is a side effect of methotrexate? I've been taking mtx for over 2 mos, just recently (2 wks ago) switching from pill form to self injections because of daily headaches I've been having for about 3 weeks and rheumy thinks the pills might be the cause. Now, to add to my problem, my blood pressure has been unusually low (100/55 & 100/48) these past couple of days, and I'm very concerned. Other than the headaches, which oddly enough I haven't today, I don't have any other unusual/new/different symptoms. I still have the ongoing dizziness due to the nerve damage and hearing loss in left ear, and I don't feel any dizzier..lol (I write this because nurse asked me if I was feeling dizzy). PC doc said if any other symptoms appear to head to the ER, and I also don't go in for labs until next week.
