Hi, Thanks for using the HCM.
I want to know since when you are suffering from it. Is it diagnosed as migraine
The pathophysiology of migraine is very complex and hence there are multiple types of medication for it and caffeine (coffee) is one of it. This acts on neuro vascular system to relieve your head ache. It may be psychological also in some time.
Hope I have answered your query. If you have any further questions I will be happy to help. Thanks get well soon....
