Finger Repair

I have successfully calloused my fingers on my left hand. However, I have indented my index finger with a string groove. With the callous not as flexible as an 'uncalloused' finger, the tough skin doesn't return to a smooth fingertip. I have probably been practicing too much. Do I have to stop playing or is there something else I can do to repair my finger? Is this a common issue with new players?
Thanks,
David

If you ain't got no grooves in your fingertips, you probably don't have the groove yet.
