I have numbness and tingling sensation in my leg when i got up to walk i had trouble and i couldnt feel it and i almost fell who should i see for this?

Could be normal: You might have just compressed your sciatic nerve - the main nerve from your spine that extends all the way to the toes. Sometimes you can sit on this nerve "wrong" and cause compression and a transient tingling and numbness. If this only happens with certain seated positions, then I wouldn't worry. If you have random tingling, numbness, pain, or esp weakness, then go see a Primary Care doc.
