Hi Shaz. First up I’m sorry that you are going through this. It’s all a bit (removed by moderator)really. Being relatively new to this myself ( 1 year and counting) I can’t offer a direct comparison between the two drugs. I’m on Tecfidera, so I’ll restrict my comments to that. The list of side effects does seem pretty daunting however most of the serious ones are pretty rare so try not to worry about them. Personally I only experienced pretty minor hot flushes before things settled down and I never had any gastric problems. What is important to note is that in the case of Tecfidera (I assume mavenclad is the same) it won’t do anything for your current symptoms rather it will reduce the likelihood of relapses in the future.
Now some positives, your life isn’t over. Yes MS will change things but I’m still pretty active at the gym as well as cycling regularly. I sometimes have to walk with a pole but my symptoms are mainly in my legs rather than hands. Concentrate on what you can still do and enjoy it as much as you can.
