You know, your situation is unique, . I know for a fact that there are other members of this community that don't take some conventional MS medications due to various health concerns (including previous cancer diagnoses and the like), so I hope if they are still active here, they see your post and comment here.
Depending on what blood issue you are dealing with, you may be able to proceed with certain MS medications, but that is for you and your doctor to decide. There are definite pros and cons to be weighed, whether you exchew conventional treatments or pursue them and only you can decide what the right choice for you and your health is. I know this isn't exactly what you were looking for, but I highly recommend the MS Navigator resource through the National Multiple Sclerosis Society -- https://www.nationalmssociety.org/resources/get-support/ms-navigator. Trained individuals can offer support and resources for people with MS and they might have some leads on groups or options for people in your situation. I know you're not the only one in this situation; I just don't know how to help you connect with others like you. So, the MS Navigtor resource may help. And again, I hope other members of this community will chime in here as well!
Best, Erin, Team Member.
