Been on Methotrexate for 3 weeks doing pills. Shots will be coming soon. Still go a lot and most of all feel achy and tired! When will I feel a change? My nurse from my ins company calls once a month to check on me. She says get of this drug sooner than later very strong stuff. Not to be used forever and get blood check once a week. Doctor's never said this to me only to get my blood checked :ybattynce a week oh well I'll keep on trucking.
