MTX and foot neuropathy

Hi all -- I've been taking MTX for 3 years now for temporal arteritis and polymyopathy rheumatica (15 mg once a week). Just recently my chemo-induced foot neuropathy jumped to a whole new level after being stable for a year, to the point where I couldn't walk for a few hours after waking up. I was wondering if this exacerbation may be attributed to MTX  use. I have found nothing useful in a cursory Google search.

I just went off of Methotrexate for RA 2 weeks ago after 18 years and now my hands are drawing. The MTX caused ulcers in my esophagus!! Had anyone used a natural alternative that has worked?
