Hi
First time on here but wondering if anyone has any advice. I've been taking methotrexate for over a year ( plus the frolic acid) without any problems. My tongue however, has started to feel sore and I'm feeling increasingly dizzy and faint. My last blood test 2 weeks ago said I needed to go back to test again in 4 weeks as B12 was low. Does this ring any bells for anyone? Any advice?
