This could be residual nerve inflammation but a post-op seroma (fluid collection) or even a recurrent herniation are possible. If you were my patient, I would advise the next step using an oral short course steroid. If no significant improvement, then a new MRI. If seroma or small recurrent HNP, the an aspiration and steroid injection.
