hey welcome michelle
sorry to hear you're having trouble.
as you've seen, numbness and tingling does not automatically mean ms, so don't worry too much on that score. it is something to take action on though. so good for you for coming on here to ask.
personally i focus on nutrition, so i would want to know about your daily routine in terms of diet and hydration. the more detail you can provide the better.
also, if you make an appointment with your doctor, they can run some tests to figure out what is going on in more detail.
if you decide to share any dietary info, i may be able to suggest some nutrient testing ideas that you could fly past the doc and see if they'll agree to have them done.
