Hi I am 62 year old. I was diagnosed with rheumatoid arthritis almost 6 yrs backand I had been taking lefra and folvite since then. Also last year I was diagnosed of shingles and for that I was given some wrong medication which reacted and I was hospitalized for 15 days. I have become quite weak after this. Since then I am not taking any other medicene other than lefra and folvite. From almost last one month I am again feeling that arthiritis pain in my hand. Can you please give any suggestion?
