A big welcome to the forum and thank you for taking the time to reach out and write about your experiences, an important step which you’ve tackled brilliantly/
I have MS and very much understand your concerns. Be aware though that there are a number of different conditions which share those symptoms and sometimes, there’s no condition at all and I sincerely hope this is the case for you.
To give yourself peace of mind, the first step I encourage you to take is to visit your GP and get a referral to a neurologist and have an MRI done of both your brain and spine. It’s completely painless and just requires laying still got about 45 mins.
Based on the results, the neurologist can decide whether there’s anything to be concerned about and whether further treatment is required. I wish you the best of luck. Please consider letting us know how you go. Take care.
