Some bloodwork to make sure all is well sounds like a good plan. Unfortunately, I am not an expert in what to look for... MS has been my first (mis)adventure in the world of medicine!
But I totally hear you on how confusing it is! I'm allergic to Copaxone, and we chose Betaseron partially because I can store it OUT of the fridge (out of sight and mind of children). I am in Alberta, Canada, so time will tell what new drugs will be funded! A crystal ball would be nice about now
All the best to you, and your tests!
