Numbness in groin area

Hi all I recently had my yearly review at shampton and told my consultant that I get numbness in my right groin area and top of leg after walking for a few minutes. Along with the numbness it aches too. He said he’d organise an mri of lumbar and sacral spine which would take about 2 months. I got the appointment for 2 weeks! I had it on Saturday. He thinks I may have a trapped nerve. Does anyone else get this? It feels tight and crampy at times around groin/ovary area going to the top of my leg x

My hip I had a xray on it expecting arthritis, not sign, the doctor gave me naproxen for the pain. It works which is great but why the pain in the first place???
