[3] [17] The inflammation can lead to the formation of scar tissue and adhesion that can make the spinal nerves "stick" together, a condition where such tissue develops in and between the leptomeninges - between dura and arachnoid or pia and arachnoid. [17] This condition can be very painful, especially when progressing to adhesive arachnoiditis.
Tethered spinal cord syndrome may go undiagnosed until adulthood, when sensory, motor, bowel, and bladder control issues emerge. This delayed presentation of symptoms relates to the degree of strain on the spinal cord over time. [4] Tethering may also develop after spinal cord injury. Scar tissue can block the flow of fluids around the spinal cord.
There is excessive scar tissue formation within the joint and/or surrounding soft tissues leading to painful restriction of joint motion that persists despite physical therapy and rehabilitation. The scar tissue may be located inside the knee joint or may involve the soft tissue structures around the knee joint, or both locations.
Sciatica is pain going down the leg from the lower back. [1] This pain may go down the back, outside, or front of the leg. [3] Onset is often sudden following activities such as heavy lifting, though gradual onset may also occur. [5] The pain is often described as shooting. [1] Typically, symptoms are only on one side of the body. [3]
The healing of trauma to the outer anulus fibrosus may also result in the innervation of the scar tissue and pain impulses from the disc, as these nerves become inflamed by nucleus pulposus material. Degenerative disc disease can lead to a chronic debilitating condition and can reduce a person's quality of life.
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
After age 50 or 60, osteoarthritic degeneration (spondylosis) or spinal stenosis are more likely causes of low back pain or leg pain. 4.8% of males and 2.5% of females older than 35 experience sciatica during their lifetime. Of all individuals, 60% to 80% experience back pain during their lifetime. In 14%, pain lasts more than two weeks.
Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
