Your symptoms could be that of recurrent hernation (about a 10% chance after initial hernation). You do have a history of pain reducing even after a massive herniation, so this pattern could be returning. You could have a new herniation at another level (groin and inner thigh could be the L1 or L2 root) but if pain radiated to foot, I would suspect the lower nerve roots (L4-S1) are involved.
You need a new MRI. Can you report to an ER to complain of this pain? If you have motor weakness (and I would hope a careful examination by an ER doctor could reveal this but don’t count on it), this would move you up in line to get a new MRI.
