I have been having back pain for the last 2 to 3 months and seems to be getting worst. while sitting for awhile my neck starts burning and feels like it is straining and my lower back starts hurting.... feels like the small curvature in my lower back starts hurting bad and my hips and legs start hurting also. And while doing activities such as bending and reaching or a normal common tasks my my back starts hurting from the lower spine all the way up and their is a burning in the neck, upper back and lower back. And if reaching I sometimes feel a jolt in the upper center of my back and my hips, buttocks , and legs, and knees start hurting.
Hello. Thanks for posting your query.  Back pain you have seems to be mechanical in nature. I would also like to give some advice to make the life better and to fight with these pains-Do regular physiotherapy of back and joints not sit for prolonged period of time in stressful postures not lift heavy weights on head or back I suggest you to consult an orthopaedician nearby for a detailed examination. You may get the X-ray of the spine under his/her guidance to look for arthritis or other changes in your spine. Your doctor after diagnosing the condition may refer you for physical therapy. The physical therapist will help you reduce your pain using stretches. The therapist will show you how to do exercises that make your neck and back muscles stronger.  You can take analgesic and muscle relaxant after discussing with your doctor. Wishing you good healthRegards.
