Dull eyelid pain 6 years after surgery - What's happening?

Hello, I had ptosis surgery in 2019 and starting this year, I started to feel a dull pain in my eyelid. I usee to get a dull pain here or there but it would go away fairly quickly so I never worried about it, but this time it’s lasting more than a few days. Also, my eye itself has started to water more lately. (During my surgery, doctor thought my eyelid muscle was detached, but once they got inside they realized my muscle was still attached and she said that made it more difficult)
