Hi Whaleharbor,
I just looked up “temple pain” very quickly and seems it can be related to the eye (possibly migraine or inflammation of optic nerve), sinus congestion (even if you don't knowingly have an infection) or ear-related. While this could well be a herx symptom, if you're concerned and it doesn't go away, the suggestion on the board I read was to see an opthalmologist to check your eyes are okay, first. After that…your ears.
Intracranial hypertension (benign) is also a listed side-effect of mino in the early stages but generally passes with time…sorry, my memory fails me on your dose, but you could try lowering the dose to see if that helps and very gradually building up again.
That's all I can think of for now…but others may be able to share more from their experience/wisdom bank.
Hope you feel better soon and this is just a transient herx thing.
Peace, Maz
