I'm very sorry to hear that you're experiencing this problem.
I don't know who you use for your medical support, but, I'd be on the phone with one Immediately!
Total numbness can be serious.
Do you have a neurologist?
After you've moved around a bit do you get any feeling? Any changes?

I'd guess that your neuro would have you go to the ER.

So, My personal answer to your question, "Should I see medical help"?
Is a Definite YES!

I hope you find some relief, and healing!

Pete
