Susie,
I remember worrying about that too. The numbness lasted so long that when asked if it seemed better, I said I couldn't tell if it was getting better or if I was just adapting to it!! Although, I could function with my legs/feet, it was just so frustrating! My doctor did tell me that it could take up to 2 years for normal sensation to return. Thankfully, I was back to normal a little sooner. Oh, the simple things we take for granted until something like that hits us!
I still have a little difficulty walking with backless shoes (flip flops)...I drag my right foot a little like I'm trying to keep that shoe on...could be a habit and could have walked like that before...idk...?? Just something I am aware of now.
I do not ever want to deal with that again either! Mine occurred 3 days after the flu and I noticed it while in a hot bath shaving my legs. I have been really sick once since then and I kept waiting for the symptoms to appear...only they didn't. I suppose that will forever be in the back of my mind during an illness after having gone thru this.
You sound like you are gaining the feeling back slowly but surely and I would be willing to bet your doctor is wrong

Give it a little more time...it's not a sudden thing b/c I think you kind of get used to the numbness and you don't notice it as much. But one day you just realize it's better...or GONE!
Hoping and praying for the best for you!
Angie
