Keep up to date with your doctor. If you think their diagnosis is wrong, see someone new if possible. Trust yourself. You know your body better than them. And it’s also possible your MS is in remission, which is why the MRI looks better now. This would make sense if you’ve been in treatment for MS. If not, maybe the lesions were caused by something that mimics MS or something entirely different. I’d just say to keep up with doctors visits and keep an updated list of symptoms with dates. And be open to anything! It could that your MS is in remission or it could be something else! Either/or it’s important to get answers. I’m sorry you’re dealing with this! My fight for a diagnosis has been very difficult as well. It isn’t easy!
