Welcome to JA and thanks for asking
It seems like you are suffering from migraine
There are two types of medicines used in this condition
One of these is to abort an acute attack and the others are to prevent further attacks.
To abort an acute attack drugs like NSAIDs,opioids analgesics,triptans,ergot derivatives and steroids are used
For prevention of attacks drugs like beta blockers,calcium channel blockers,anti seizures,anti depressants,and certain pain reliever are used.
If beta blocker is not working then consult your doctor to switch to an alternative drug among the ones i mentioned
Feel free to ask if you have any more question
Please leave a POSITIVE (3 – 5 stars, preferably 5) rating by clicking on the stars above, until you do i am not compensated for my time. You can continue to ask follow-up questions even after the POSITIVE rating
Another thing which should be considered is a sinus problem as it can lead to a unilateral headache as well. Pressure rises in the sinuses when you sneeze and that can worsen the headache so it won,t be a bad idea to see an ENT doctor as well
The system says that you requested a new expert.
If your GP thinks that these are not migraines, what is the reason for using a beta-blocker?
When used for headaches, beta-blockers are typically used for migraine or other vascular headaches.
Intense short headaches are frequently referred to as ice pick headaches, although the proper medical term is primary stabbing headache. These most often often occur as a part of a larger headache syndrome, and most often associated with migraine headaches. However, they can occur with other types of headaches.
Since they are of such short duration, it is usually difficult to treat these headaches with a medicine designed to relieve the headache, so the treatment is usually oriented towards that larger headache syndrome with which they are associated.
If you do not have migraine headaches or other vascular headaches, the doctor may have tried the beta-blocker to cover for the most common associated headache syndrome. Since the beta-blocker is not helping, then the next step would be to try an alternative preventive medicine.
It is true that sinus disease can cause chronic headaches, although only infrequently associated with ice pick headaches. But since you have rhinitis and an association of headaches with the need to sneeze, it would be appropriate to consider further evaluation or treatment by an ENT physician.
Another common headache syndrome are muscle contraction headaches. Ice pick headaches can be associated with muscle contraction headaches, although not as often as with migraine headaches. Sneezing can make muscle contraction headaches worse, but it is usually with the sneeze, rather than preceding the sneeze.
It would be reasonable to discuss with your doctor about the use of medicines to prevent muscle contraction headaches, such as amitriptyline or duloxetine. These are antidepressant medicines, but have also been shown to be effective at preventing a variety of chronic pain syndromes, including muscle contraction headaches, and it may help prevent any associated ice pick headaches.
If I can provide any additional information, please let me know.
Is there any further assistance that would be helpful?
