Sciatica is a common medical condition that many people suffer from. While it can be very troubling and distressing, it rarely progresses to a state that causes physical limitation or permanent damage. Regardless, I would recommend that you have this evaluated by your primary care doctor
. He or she can help determine if there are any reversible causes of this as well as potentially give therapies to alleviate your symptoms.
Sciaitica is a general term that loosely describes a set of symptoms where one has numbness
or tingling sensation in the leg. This term is invoked when these symptoms are thought to be caused by nerve impingement in the nerves that feed the leg. It is caused by compression of these nerves as they leave the spinal cord (in the back). As such, this is often caused by degeneration of the spine (bones of the back). The numbness and tingling you describe is known as a parasthesia -- and is classic for sciatica.
There are many treatments for sciatica. Paramount is alleviating the compression of the nerve in the back. What can also be done is medicines to decrease the nerves irritation. Physical therapy is often helpful.
If you have any weakness or changes in your pooping or peeing -- please see the emergency room immediately.
