Sorry to hear you are in pain. I have severe arthritis for over 20 years and I also have pain in my groin area that comes from my back. If you think about it the back runs around to the groin area if you feel around from your back to the front, it runs right into the groin. The numbness on the outside of my thigh mostly one thigh, could be from the siatic nerve. I also have to get in my recliner and it helps to releive my pain. I have ran out of medication and I know ahead of time I will have to sleep in the recliner it's a life saver. I'm no doctor but do you have arthritis? It is unbearable across my whole lower back and I have it in both leggs. If you bend over and on the way back up does it hurt a little low in your back? I hope this helps but like I said I'm no doctor maybe this will help some. Good Luck
Hi
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 or soft 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.
What I would like to add is that the nerve compression may be superficial too (lateral femoral cutaneous nerve), that comes from the hip area and gets pinched. This condition is called meralgia paresthetica and is often due to weight gain or wearing tight clothes and belts. Losing some weight or wearing loose clothes and belts often helps relieve the pain/numbness/tingling. Also injection of lignocaine (anesthetic agent) at the site helps. Please consult your PCP for primary examination followed by proper referral.
Take care!
