I have had exactly the same symptoms for about a month now. although i dont get vertigo.. I too keep getting regularly these pressure headaches, especially at night and when i wake up and they last only for a few seconds or minutes...
Did you get yourself checked up ? What can be the cause ?
The usual 'red flags' for a headache that might indicate a serious cause are new headache after age 40 years, 'worst headache or your life', sudden severe onset, an abnormal neurological examination (for instance focal numbness or weakness), fever, or a seizure.
Seeing your doctor is a good idea as he can do a neurological examination and help decide wether the headache is just related to tension, sinus, local infection (eye junk), migraine, or cluster headache.
I forgot to mention that I'm a 22 year old female
