(First of all, I am 50 years old, and have been physically active all my life: running, swimming, biking, outdoor activities, etc. I have mild arthritis in hips, but am able to stay pretty active with no severe pain.) For about 1 week now, I have felt a weakness/numbness/sometimes tingly (like leg falling asleep) in left leg, stemming from hip area. I m hoping it s a pinched nerve, as I was fine one day, and noticed it the next (not a gradual sensation). I ve been stretching but it hasn t helped. Feels weak when climbing stairs. Unable to jog, leg feels like it could give out - weak. No pain or discomfort whatsoever however. If it is a pinched nerve, are there certain exercises I can try at home to alleviate the problem before I go spend a fortune for an examination?
