Note 3 at Ac 14:20: This had to be a very miraculous healing of the Apostle Paul. The Scripture doesn't say that Paul was dead, but if not, he was so close to death that the ones who were trying to kill him were satisfied that he was dead. Yet Paul rose up on his own and the next day traveled to Derbe, twenty to fifty miles away (see note 5 at Ac 14:6). To walk or ride that distance would be rough on a healthy man in good shape, but it would have to be a miracle for a man who had been stoned and left for dead the day before.

This leaves no doubt that Paul received either a resurrection or a miraculous healing, yet it is possible that when he arrived in Derbe, his body still bore some signs of the stoning and was still in the healing process. This is probably the infirmity that Paul made reference to when he wrote to the Galatians (Ga 4:13-15) and may have accounted for some of the scars that he said he bore in his body (Ga 6:17).
