Hi Doctor, Have been through severe pain in my left hip over last 10 months. It erupts in a specific posture which is difficult to predetermine what will lead to pain. On thing is for sure, while turning around in the sleep, the pain gets excruciating and I generally get up with the pain. Also, I fell it during walk. However , if you ask me to stretch my legs in any position, there is no pain. Also, I don t feel any pain by pressing any point. - I have a decent flexibility as I ve been practicing yoga over last 2-3 yrs and have been leading a active lifestyle. Wt 78 kgs and ht 6 ft - MRI, hip X-ray , high frequency Ultrasound has been done and nothing has been found out so far. - ankylosing spondilytis, sciatica, piriformis syndrome, weak lower back muscles, buldge disc - all has been ruled out. Have been getting contradicting views . no idea on - should I do mild exercise or avoid it completely till the pain subsidies. - how should I deal with pain? - to long should o take pain killers and which one to take? - what might be the real problem and how will that be detected? End all - what should I do at how should I proceed further. Thanks for your time.
