No direct experience, but it could be blood sugar related. Do you notice it more when you're hungry or haven't had a solid protein meal in a while? Protein helps to stabilize your blood sugar. Or conversely do you notice it after you've eaten and perhaps especially after a meal that might be higher in sugar than usual? What about hydration? How much water are you drinking per day? I aim for 3-4 L of water, especially in this heat! Speaking of heat... do you notice it when you're more active outside or the opposite, haven't gotten outside for a bit of exercise?
I would start by experimenting with your diet and if it doesn't go away soon, definitely talk with your care provider.
