@Nat6999 it’s a worrying time I know, 
I was initially dx with Transverse Myelitis, after experiencing complete numbness which spread from under bra line to pubic bone, I also had numb fingertips, difficulty walking, numb thighs etc.
My family have been in a private health scheme for many years, so I was lucky to see an excellent Neurologist within a week, I had MRI of Head, Cervical & Whole Spine, 3 days later and saw Neurologist again for followup 2 days later.
I was also concerned about MS as I had googled my symptoms. Whilst the Neurologist dx me with TM at that time he thought it was a first presentation of MS, and immediately referred my to my local MS nurse Specialist. I took high dose steroids to bring down the inflammation in my spinal cord, and got on with life. I am married & had two young DS’ at the time.
In less that two years I had a relapse of visual symptoms that came on really suddenly, and lasted a few days, double vision, couldn’t stand up, awful vertigo. By the Monday everything was fine again, I couldn’t face going to see Neurologist, as we were about to go on holiday, when I returned I had a letter from MS Nurse asking to see me, when she visited I explained the recent symptoms she said see Neurologist it sounds like a relapse. Saw Neurologist, had MRI, a further lesion was found and RRMS was dx officially.
I choose Rebif as my first DMD, injectable drug, 3 times a week, gave me some skin problems & didn’t control the disease well enough for me. Unfortunately at that time the only options were injectable. From the time of choosing the drug with the help of my Neurologist & MS nurse, they arranged a visit from the drug from to help me do the injections, really easy the machine called Rebismart does it for you, so you don’t see a needle. This took about 3 weeks or so.
As Tecfidera (my current) DMD was awaiting approval, I have been on Tec
for 4-5 years, tablet twice a day, and MRI haven’t shown any change, yay! I did experience side effects with the Tecfidera initially, but they are much better now, flushing, nausea etc.
They are many more MS drugs available now So options have increased, should you be dx with RRMS, usually they start with frontline drugs ie injectable, unless your MS is very active, I would recommend Tecfidera as it convenient, one tablet morning & night, and had had a good effect of controlling MS for me as proved by MRI.
Good luck I hope you feel a bit better soon. Try not to panic would be my advice, not everyone with MS is in a wheelchair. You can still live a good life, with the right adjustments.
Wishing you all the very best.
