Thigh nerve pain. Or just neuropathy?

Hello Sir/Ma'am, I have a l5-s1 disc bulge and the bigger problem which I am facing right now is that I have thigh nerve pain, doctors say the thigh nerve pain is due to my disc bulge, I don't know whether it is sciatica nerve pain or femoral nerve pain or something else, my symptoms are only in thigh I get nerve pain (more in right leg) and some tingling in my right foot, also couple of months back I had peripheral neuropathy which was detected through ncv test than after 2 months I again did ncv than it said I had no neuropathy. My question is can anyone please help me out with my thigh nerve pain and is it due to sciatica or femoral nerve or just Neuropathy? Please do let me know as to what exactly is my problem. Kind Regards, Manas.
