I don’t presume to give advice to a person about their body and health — that’s what doctors are for. However, this isn’t a cyst that needs to be surgically removed. Could a temporary change in your lifestyle — like doing water fasting for a few days — help your body enact its healing powers?
You said yourself that you still need to take care of stuff before you can even schedule this revision. Perhaps this is the best time to try something like this and see how your body reacts to just daily lemon water.
It could change your life.
And it could not.
It’s your call.
Good luck!
