Hi there!
Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include primary cranial headaches, vascular issues, high blood pressure, neuro-muscular causes, electrolyte abnormalities, hormonal/ endocrine abnormalities, micronutrient deficiencies etc. I would suggest getting this evaluated by a primary care physician initially and depending on the cause diagnosed/ suspected, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.
Take care!
