Pinching of the S1 nerve causes weakness in the ankle and numbness and pain in the sole and side of the foot
Sciatica is caused by compression or irritation of the sciatic nerve, which is the largest nerve in the body. This can result in pain, numbness, or tingling that radiates down the back of the leg. Common causes include a herniated disc, bone spur, or muscle imbalance.
The most likely cause is a lower back disc problem (usually the disc between L4 and L5, or the disc between L5 and S1 ... L stands for lumbar vertebra, and S stands for sacral vertebra). The disc presses on the nerve root outlet, and this causes pain to go down the leg. If the disc presses the left nerve root outlet from the spine, then the pain will be felt in the left leg. If the disc presses the right nerve outlet from the spine, the the pain will be felt in the right leg. Accurate diagnosis involves a CT scan or MRI (but you may not even need one, if the pain doesn't occur in your normal everyday life). The best treatment is to avoid the movements which cause pain, and to do back exercises provided by your physician. Only in extreme cases is surgery helpful (which shouldn't be needed in your case, because the pain only occurs in particular postions). In any case, check with your doctor about what do next, in your particular case.
The S1 unit for mass in the International System of Units (SI) is the kilogram (kg).
A herniated L5-S1 disc can cause symptoms that radiate into the buttocks and legs, but it typically does not directly cause pain in the bladder or prostate area or extend into the urethra. It's more likely that symptoms related to the bladder, prostate, or urethra may be due to other factors unrelated to the disc herniation. If you are experiencing these symptoms, it's important to consult a healthcare provider for proper evaluation and diagnosis.
Hit tendon nociceptors in tendo-achilles. It goes to the CNS by sciatic nerve, then it goes to interneurons in spinal cords S1-S2. Then it goes to Alfa motor n, tibial nerve from sciatic nerve to lead to the gastrocnemius muscle.
disc is herniated ( sticks out further than what its supposed to meaning it sticks out past your vertebrates) and it has your nerve pinched. I'm going to guess that you have leg pain as well right? lol had the same problems, just had a L5 S1 fusion
The nerve pathway travels down from the s1 spine. If the nerve root at the s1 is impinged or herniated, symptoms of sciatica can appear.
Absolutely not. Though the pain is felt in the legs and foot, the Sciatic nerve and resulting pain from it is due to nerve compression from the L4/L5 or L5/S1 disk on the nerve itself. Operating on the wrong body part won't do anything but make you feel worse.As a person with a long history of spinal and pain problems, I will also tell you that you should NEVER consider surgery for back pain unless you are at the point where there are no other options available.
Evidence of impression on the L5 and S1 nerve root on the right at the L5-S1 level typically includes imaging findings such as a herniated disc, foraminal stenosis, or a mass effect from adjacent structures. On MRI, this may present as displacement or compression of the nerve roots, along with associated edema or inflammation in the surrounding tissues. Clinical symptoms may also be evident, including radicular pain, numbness, or weakness in the lower extremity corresponding to the affected nerve roots.
You may have a disc protrusion at L4-5 or L5-S1 which is impinging on the nerve(s).
the common peroneal nerve and the tibial nerve:Common Peroneal Nerve, comprised of nerve fibers from L5, S1, S2, and S3.Tibial Nerve comprised of nerve fibers from L4, L5, S1, S2 and S3)
The nerves coming off the spinal cord at L5 and S1 are being pushed out of their normal position.
It means that the disc between L5-S1 has protruded out to one side (not centrally), and is affecting (most likely compressing) the S1 nerve root which is below the level of the herniation (the L5 nerve root has already exited the IVF). From this report I am assuming you are having some sensory or motor problems in your lower limbs?!
The S1 nerve is the first sacral nerve. It leaves the the spine via a foramen in the top fused bone of the Sacrum. The sacrum forms the posterior part of the Pelvis and this is where the Root nerve S1 can be found before it quickly joints the lumbosacral plexus.

USUALLY (note the caps) a herniated disk will retract on its own, releasing pressure on the nerve, and the pain will disappear. this happens about 70% of the time. The disk will then scar in place, and you should not be bothered again. Occasionally a numb area (where the nerve went) will remain after healing.

The sciatic nerve is formed by the merging of several nerves in the lower back and pelvis, including the L4, L5, S1, S2, and S3 nerve roots.
