I think you have to be aware that there are many, many symptoms associated with MS. And an awful lot of those could also be caused by other diagnoses. Even some vitamin deficiencies can look like MS (D or B12 primarily).
Essentially, you need to be referred to a neurologist, have a neuro exam and whatever tests the neurologist thinks are necessary and only then will you (hopefully) know whether it’s MS or not.
Until you have had the tests and a diagnosis from a neurologist, it’s not a good idea to get it fixed in your head that it is MS. It might not be.
Many people do see a neurologist privately initially because it’s quicker than the NHS, but before you go down that route, you need to know how long the waiting list is for an NHS consultation (because if it’s relatively short you could end up getting diagnosed quicker). If it’s too long, then find a local MS specialist with both a private and an NHS practice. You’ll still need your GP to refer you, but it might be that if the neuro wants you to have an MRI and other expensive tests, they can slot you into their NHS practice. This way, hopefully you can only pay for an initial consultation.
It certainly is a worrying time to have unexplained symptoms for months. And for them not appearing to change or improve in that time. But, it’s a case of trying to put it from your mind as much as possible, keep yourself as fit as you can, given the symptoms you have, eat and sleep well.
And supposing it is MS, it is most likely to be relapsing remitting. Remission from a relapse can take months and months. You can find symptoms have remitted almost by accident, you wake up one day and find that you can feel some part of you that you couldn’t for a long time. And you maybe weren’t aware of when the feeling changed. And there are some symptoms that just don’t entirely remit. Sometimes you manage to compensate for the symptoms, and other times you can’t.
The best thing about RRMS these days is that there are many disease modifying drugs to ward off relapses. So you could find if you do have MS, things only get better from where you are now. And don’t forget, it might not be MS.
