Good Morning Paniccu
IMHO, it seems to me like you need a work up to identify what is causing the problem. Be prepared to tell your physician your family history, medications your on, the onset, and duration of the numbness and pain. Doe the numbness and pain bother you most when sitting down or standing ? What makes it better and what makes it worse?
Any other physical or mental stress going on in your life right now besides this concern?
You have posted you had sciatica nerve pain in the past and this does not seem the same. There are many things that could cause these sx and I am not a professional and don't want to guess. I am just glad your going to seek help. ((((((((((HUGS)))))))))))
When you go to the Doctors, keep in mind your there to find out what is wrong and the Doctor is working for you and with you. Take deep breaths and write down your notes about how you have been feeling and questions you have.
You will do well and please keep posting as we need you here and the members are all here to support you.
