Did it blow the spark plug completely out of the head? If it were me id go back to the shop where it was done and hold them to fixing it properly. It sounds like they may have stripped out the head putting that plug in. This is fixable but also the putts may be caused by the old plugs if they were left in there or a coil pack/packs going bad. Those are on top of each plug and are very easy to replace, available at local parts houses
