I have had numbness above my knees for sometime now but last week I started getting sharp stinging pain and pins and needles together with the numbness. I get a warm feeling from my abdominal area down the from parts of my legs also. This pain is excrutiating! It is driving me up the wall. My feet and knees are also swolen. I need a diagnosis for this a.s.a.p. because I don't know how I will be able to do my work on monday.....it is getting worse by the minute.
