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.
If a cyst breaks open, it can cause pain in the back of the knee or down the leg. If a cyst is large enough, it can lead to swelling in the leg and foot. Ovaries â When ovarian cysts rupture, they cause sudden, severe pain in one side of the lower abdomen or upper pelvis. Ovarian cysts are associated with menstrual spotting and irregular menstruation.
