Sorry to hear things haven’t been so good. I haven’t been on here much lately but came on looking for guidance on Tecfidera as I have appointment about it later today. I saw you name at top of listings. I was going to pm you but can’t work out how on new site…yet. I have had symptoms you describe.
When I had palpitations I also had other symptoms of dizziness and more importantly breathlessness which is not an MS symptom. It could be just an MS sensation you can get buzzing and fluttering sensations etc but it is always important to be aware MS doesn’t stop you getting other things so you should always get things checked out properly if you have any concerns.
Anyway if you fancy a chat hopefully you still have my number…and that I have right Michelle! Sorry if I haven’t!
