[|Human|] Im wondering why my lips keep cracking in the two corners over and over. I get them to heal and then they crack again. I  recently (8weeks ago) had my fifth surgery due to cancer... a Latissimus Dorsi Muscle reconstruction surgery. My doctor (LOVE him) used Exparel this time although Im NOT sure that has anything to do with it?... I need to get some relief that is permanent!
