Thanks for your prompt response!! You are absolutely correct my leg pain become worse when I stand or walk. I cannot stang for more than 15 minutes and walking above 70-80 Mtrs is tough.The action which causes the pain is driving car and climbing stairs. one of the reasons- this time it is aggravated becasue of climbing of stairs to 3rd floor for 15-20 days At times i get some releif when I sit. But now a days during that also i need to change posture and need to sit in curved posture. Also i can not sit for 20- 25 minutes at a strecth, without support at back. I have sent you some MRI snapshot in e-mail, i am not aware how to attach them in this forum…Also can u please throw some light on ozone therapy…Thanks!!!
