I have had 6 months of injections and so far so good, with no side effects. I also met someone at the infusion center where I go, and she also has had no side effects and has taken almost a year. I have my next scan in May and am hoping that my numbers improve significantly, especially in my spine.
Not sure whether you are aware, the injections are in the back of each arm, so I would recommend wearing a short sleeved shirt so that it’s easier.
Good Luck and please keep us updated.
