I had cough since nov. 2019 and got checked with md after hrct and other tests .he diagnosed me with ra- ild .and he started with wysolone and prefridone .i got relief. For further satisfaction I got checked at rheumatology dept. In pgi chandigarh on 6th jan. 2020 and after series of tests ra-ild was confirmed and I was asked to stop prefridone and continue with wysolone along with meconerv. Want to know that the supplement b12 alone alongside wysolone is good enough for my ailment.
