When I was on immuran & methotrexate, I lost hair, over my ears & hair line. The doc. got me up to high on these meds. & I had liver trouble, this caused extreme weakness, & a shaky feeling. Sure enough they did blood work & my liver had been effected. We skipped a week & he lowered the dose by 1 pill the next, then I was fine.
Hope you get feeling better, blood work is very important with those meds.
