Symptoms of Spinal Cysts. Patients with a spinal cyst may not experience any symptoms if the cyst remains small and stable. As the cyst progresses and becomes more severe, it may cause pain in the back that travels down the legs as well, and can also lead to spinal stenosis, which may cause pain, cramping and numbness.
The cysts can affect the release of a mature egg from the ovary and cause a temporary halt in the menstrual cycle. Lower back pain is very common in women who suffer from ovarian cysts especially if the cysts grow large. Large cysts tend to press down on the nerves of the lower spine and this can lead to pain. The pain at times can be excruciating and unbearable and should be investigated by a doctor.
