Welcome to the Pain Management Forum. I am sorry to hear about your new pain.
Pain is our bodies way of signalling us that something is not right. Your body could be telling you that you have strained a muscle or that you could have a smoldering kidney infection or even a gastrointestinal problem. There are many possibilities.
I encourage you to see your PCP. He/she can provide you with more definite answers. I am sorry that I cannot do so. Please let us know what you discover.
I wish you the very best and hope to hear from you again.
Welcome to the MedHelp forum!
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. 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.
If you have gut issues like bloated abdomen, loose stools etc then it can even be IBS or Crohn’s or colitis.
It is difficult to comment beyond this at this stage. Do consult your doctor to find the exact cause. Take care!
