Hi
Welcome to the MedHelp forum!
The lower temperature and shivering could be due to the pain medication. Yes, it could be a kidney infection but if the pain persists despite treatment then other causes will need to be looked into.
There is a chance that you have compression of the spinal nerves in the lumbo-sacral spine region. This can happen due to overuse of the lower back as in work requiring too much of bending, lifting weight, fall on the back, overweight, canal stenosis, bone disease, spondylosis, poor posture etc. Poor posture while sleeping, sitting on computers or jobs for a long time, uneven bed, exposure of back to cold air while sleeping can cause a discomfort for a few days. Take a multivitamin, plenty of fluids, and an OTC analgesic. Apply a local analgesic and apply a heating pad and see if it helps. If this does not help, consult a neurologist. A MRI of the spine will be definitely required and nerve conduction studies may also be needed. The treatment is to remove the compression. You have to discuss the best treatment option with a neurologist, which can range from medication to physiotherapy to traction, lumbar belts, lumbar corsets or even surgery.
Take care!
Thank you. I got them checked, ended up being a pretty bad kidney infection.
you might want to go get your kidneys checked...
