I have been having a weak feeling in my left leg for about 4 months now, it is not stopping me from my day to day activities I play vollyball and run on a treadmill when possible. Thats what makes this feeling so puzzling to me, it almost feels like I need to limp as I walk, my right hip started popping as I walk about 3 weeks ago cant tell if its muscle or bone related. My question is that I drive a pick up 8 hours a day for my job with no lumbar support and have had some back pain on and off that has caused me to see a chiropractor. Could this back pain be causing this sensation in my legs? I have seen my doctor about this situation and after a CT Scan to check for clogged arteries, a brain MRI, A spine MRI, Nerve Conduction test, a Colonoscopy, Endoscopy,  gall bladder testing, and blood tests all they have come up with is a vitamin D defieciency, and my gall bladder is only working at 22% but they feel it does not need to come out, my Tyroid is in normal range but on the borderline of being low. This sensation is very bothersome and I fear that it will get worse even though I have been tested for practically everything. Could my job of sitting all day long driving be causing this problem and if so what can I do to help with it. I probably dont exercise as much as I should and my flexabitity is terrible. Any suggestions would be appreciated..
Since having pain in back and feeling weak of leg might be the cause of sciatica too you need to avoid treadmill for few days until your pain subsides wear back support while Chat Doctor.
