Front Thigh nerve pain. Something else?

Hello Sir/Ma'am, I have a l5-s1 disc bulge due to which I get back pain when I sit for long time like 2/3 hours but the bigger problem which I am facing right now is that I have Front of thigh nerve pain( both legs) but little bit more in right leg than left leg, doctors say that my front thigh nerve pain is due to my disc bulge, i don't know whether it is sciatica nerve pain or femoral nerve pain or it is peripheral neuropathy. Couple of months back I had severe thigh nerve pain than I did NCV and EMG test and it said that I have peripheral neuropathy than again after couple of months I did both tests again than the result came out that there is no indication of peripheral neuropathy. My symptoms are that when I walk, sit or stand for say like 20/30 minutes I get pain in my front thigh, sometimes I also feel some weird sensations in my thigh like I can feel my thigh nerves, also my thigh area muscles feel loose when I walk. So is this due to sciatica or neuropathy or something else?
