It's best to consult your doctor immediately about the issues you're having. The sooner you start a treatment, the better the chances are that you will have slower progression of the disease. The side effects of all meds are different, so it depends what you'd be taking. But in general, it's a good idea to start a therapy rather than to wait until your symptoms get even worse.

All those worries may come true but the likelihood is that you won’t be in a chair and will still be able to walk. I lost my walking capability for a couple years when I a bad year - I could not “go for a walk” but now I am on effective treatment I have recovered enough to walk 7 miles with some rests. Just keep swimming 🐟🐟🐟🐟
