Confused and scared

I am a 36/f who's been going through a Ms work up since September 2024 due to the fact that I had a car accident in July of 2023 due to my accident and having pain in my shoulder they ordered a mri that showed a lesion on my c2-c3 area and was 3mm bigs I was refered to a neurologist who then referred me to a ms expert who order another mri in novermeber 2024 and the results were still the same since then I had blood work done a nerve conduction and some other tests I had tingling feelings in my left hand and foot for a couple months but it's also been a couple of months since it's stopped now I'm just experiencing a shocking feeling in Random parts of my body from time to time mainly foot and hand but that has also slowed down a lot I just had another mri done 5/1/2025 and it showed that my lesion shrunk in size from 3mm to 1.5 and I other lesions I don't see my doctor til June 4th I guess my question is did anybody with ms ever going though this before being diagnosed like did lesions shrink without the use of medication is it possible that it could be something else that caused my lesion I'm sorry I know my message is all over the place I'm just still very nervous and I know the fact that it shrunk is a positive sign but I also don't want to get happy for nothing til I see my doctor thank you so much for your time and im sorry that my message is so long
