Hi,
I think it is nerve root pain.
Nerve Root Pain - nerve root pinching / irritation / compression / trapping is always associated with signs of nerve dysfunction (not working properly) such as pain, tingling, numbness, and weakness. The causes of the irritation are: - within the spine Annular Tear (small disc tear), Disc Prolapse (herniation), Spinal Stenosis (narrowing of the internal diameter of the spinal canal) among others. Spinal Nerve Root Pain (Radiculopathy) can arise when nerves become pinched or trapped within the bony spinal canal or vertebral column:-
L4 to S1 nerves in the lower back cause Sciatica in the hips and legs.
It is advisable for you to do physiotherapy for relief of pain and spasm of muscle, pain killers and pain management specialist for conservative management.
Hope this helps.
Bye.
i'm suspecting a bulging disc or an inguinal ligament impingement causing that numbness..if it's a bulgng disc, possibly, the posterior part of your legs(back of your thighs) will become numb. if an inguinal ligament, it can be the front part of your leg..in short, consult your md for a neurology consult. so now, dont do any lifting unless you see your doctor and have an mri to confirm results. take care.
