think this is the right place to put this. ive been on Imuran for 3 weeks now and just yesterday i started to get pain in the back of my neck like right up above the top where it meets the scull and it sends pain like a headache coming on and it hurts to move the head to either side, i have got the chills with it plus so tired just want to sleep all the time. is this a side effect of the usage of Imuran? has anyone had this side effect before if it is one? should i be worried here? im thinkin of just stoppin Imuran tomorrow, do you have to be weaned off of it like Predisone? or can you just automatically just stop? please any advice would help thanx.
