Headache at top of head

Hi, im a 21 year old male. I am suffering from some health anxiety at the moment after having an awful experience with weed and its triggered all these things off now. i was just wondering i seem to get this headache at the top of my head near the crown of my head. its not there all the time but it does seem to come back there and after i have drunk alcohol, when i have a hangoger i get a bad headache there? It doesnt stop me fom doing anything its no where near that bad but as i am anxious at the moment it does play on my mind. Ive been to the doctors quite a few times and they say that they are not worried at all but it does play on my mind. What type of headache do you think this could be? Is there anything to be worried about?
Thanks

Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.

Without the ability to examine you or obtain a history, I can not tell you what the cause of your headaches are specifically.  That said you seem to note some important associations including after drinking alcohol and in the setting of anxiety after marijuana usage.  Naturally if your headache occurs less often or less severely when you don't use these substances, that is certainly an important first preventative step.  These substances could certainly be the cause of your headache if not at least an important exacerbating feature.  If, however, your headaches continue after discontinuing the use of these substances, the severity and frequency of your headaches may direct any further treatment.  That is, if you're having to use over-the-counter pain meds (e.g. Ibuprofen, tylenol, etc) more than twice a week for your headaches, these medications can actually cause headaches.  Accordingly, if your headaches are very severe and occurring more than twice a week requiring treatment, then a prophylactic medication to prevent headaches may be useful, especially if your headaches have migrainous features (which you don't mention).  Assuming you don't have any additional associated features of your headaches and they have been occurring for quite some time, they are very likely benign in nature and not something to worry too much about as your other physicians have suggested.
