I am on week 3 of methotrexate by injection (low dose)
I have developed a severe pain in my side in the rib cage. It hurts to take a deep breath.Having a very hard time deciding if it is the mtx , the pmr or the prednisone.
I haven't had any other side effect with the mtx.
I had this once before a year ago and the dr. at the hospital said it was Costochondritis and gave me a steroid shot. It cleared after awhile.
Now the dr. say it is possibly a ligament problem but offered no help except for a muscle relaxer.
I was wondering if this is a side effect of mtx that others have noticed.
Thanks for your reply.
