@lisash Ouch! How uncomfortable for you, and if it was me, I would be hesitant to do things in fear it will act up again, right? It sounds like maybe over time the injury has rubbed some nerves? Like @artscaping mentioned, perhaps a visit to urgent care would be in order to gain some relief. Being a caretaker is difficult enough, without having pain yourself. Have you tried any capsacin type heat producing creams/ointments, to give you some temporary ease?
