Sciatica is a symptom of an underlying medical condition.
It refers to pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg. Typically, sciatica affects only one side of your body.
Sciatica most commonly occurs when a herniated disk, bone spur on the spine or narrowing of the spine (spinal stenosis) compresses part of the nerve. This causes inflammation, pain and often some numbness in the affected leg.
Although the pain associated with sciatica can be severe, most cases resolve with non-operative treatments in a few weeks. People who have severe sciatica that's associated with significant leg weakness or bowel or bladder changes might be candidates for surgery.
Sciatica occurs when the sciatic nerve becomes pinched, usually by a herniated disk in your spine or by an overgrowth of bone (bone spur) on your vertebrae. More rarely, the nerve can be compressed by a tumor or damaged by a disease such as diabetes.
MsSofieLee, if indeed you have been told that you suffer with sciatica, it is not the cause of vaginal bleeding in between periods. For that problem, you must speak with a gynecologist.
That is a serious issue that must be evaluated and treated.
Also sciatica should not have any effect on your sexual activity. You may have to try different positions to be comfortable.
