Thanks for writing your query.
are single sided headaches. You have mentioned that you have diifficulty even in brushing your hairs. Your headache seems unlikely due to migraines. It indicates more of a neuropathic pain
You should get yourself exained by a Neurophysician.
In addition to pain killers like Ibuprofen one tablet twice a day after meals, you can take methylcobaline preparation along with pregabalin
after discussing with your doctor.
