I am 4 weeks post-op today. I have been having daily headaches, usually starting in the early afternoon and lasting until I fall asleep. Tylenol doesn't help them. I'm getting my water and protein in. I don't know what may be causing them, but it seems to have started after surgery. Anyone have any tips or advice? I don't really want to spend $40 to see my doctor about it since they're not like migraine-bad, but I may need to if they don't stop.

Has your caffeine consumption changed? Coffee, tea (black, green, or white), chocolate, etc.

We can develop sensitivities to foodstuffs that never bothered us before. Artificial sweeteners are something to consider...

Are you diabetic or pre diabetic? I was prediabetic preop and had headaches before my meals which went away once I started eating. I this sounds familiar, it could possibly be your blood sugar dropping. If you have other symptoms like dizziness, weakness, moodiness, sweating, it may be worth checking out.
