<s>[INST] Hello Doctor,   I have an excruciating pain in my lower/mid back when i move a certain way. This started 4 days ago. at certain times i am unable to stand up straight and have to walk stooped and slowly. I have been experiencing a very stiff back on waking for a couple of years now.  I am 56 years of age and female. I have not been lifting or doing anything unusual physically.  I was told about 5 years ago that i had spondulitis at the top of my spine just below my neck . I do not know if there is any connection. I would be extremely grateful for your thoughts and ideas on what could be wrong.  With Gratitude   Ann Hannah [/INST] Welcome to Chat Doctor. This appears to be a problem with the lower spine, the lumbosacral area, it could be secondary to disc herniation or spinal nerve root compression. Spondylitis of the lower back may also cause such problems. It would be prudent to consult your PCP/Orthopedic Surgeon who can examine and investigate you. NSAIDs like ibuprofen and muscle relaxants like Carcinoma/Thiocolchicide would help in relieving the pain in the meanwhile. </s>
