sounds just like me... I have L4 and L5 disk damage and it affects my sciatic nerve down my left leg... I cant even feel my leg some days it gets so bad... get your sciatic checked!
Hi Lilith56,
I'm wondering if the Doctor has done any lower back imaging for you. It sounds like a classic case of a disc problem but then again I could be wrong as I am not a Doctor.
The groin issue makes me think it not the back. Hernias can produce these types of symptoms as well.
Go back to your Doctor or even a new one for a second opinion and request them to do some x-rays or other imaging.
Good luck to you,
