I understand how stressful this is for you because I’ve been down that road myself.
I would do a diary
And in the diary, I would write the date. Did you have any problems during the day? What were you doing before the pain returns? What have you eaten or drank?
I would also do my blood pressure
Then go back after two or three months and see if there is anything that is standing out that might be causing it.
Like a stressful day at work, did you eat something that day that maybe your body don’t like. Did you do a big workout say hours before?
These might help you to figure it out
And yes, stay away from AI I prefer Google
I hope this gives you some ideas as how you can be your own investigator on your life
Wish you the best
