Could Headache be caused by Oral Vit B Complex vitamins

I generally suffer from Headaches and Migraines on a regular basis, Recently I started feeling very drained and fatigued. The pharmacist suggested Getting a multivitamin to boost me. I went for an effervescent tablet that focusses on B Complex. It seems Ever since I started taking them I have very severe headaches that actually drive me to tears. The pain is mainly across my forehead and behind my right eye .Is it possible that it is caused by these vitamins? The content is as follows: B1 6mg,B2 6.5mg, B3 16mg,B6 3.4mg, B12 5ug,Pantothenic acid 5mg, D3 2.25ug, Calcium 95mg, guarana extract 475mg, caffeine 95mg. I take one tablet a day dissolved in water as per the instructions. Taking OTC painkillers seems to ease the pain a bit but does not take it away. These headaches are on the verge of driving me insane. I consider myself to have a fairly high pain threshold, but this constant pain that just does not budge is taking its toll.

Dear Annie,

It is quite possible that the multivitamin tablets contain something that triggers the headaches - the only way to be sure though is to stop taking them and see whether the headaches improve.

It is possible though in most patients to treat the migraines successfully so that they no longer occur - to do this we have to diagnose where the pain is coming from.

To get to the root of the problem, it is necessary to undergo what is called a “multidisciplinary assessment”, which should include a neurological examination to rule out any serious underlying condition. There are so many different structures in the head and neck, all of which can be involved in the headache process, that no single specialist can have all the knowledge necessary to make a comprehensive assessment and diagnosis. For instance, a neurologist will examine the brain and nervous system, a physiotherapist will look at the muscles, a dentist will examine the teeth etc. For this reason, the “multidisciplinary assessment” combines and integrates the expertise of different specialists who would normally treat headache patients in isolation, into a single more comprehensive body of knowledge. This enables the different members of the team to provide a co-ordinated treatment plan, so that all the contributing factors are addressed.

This assessment must include a thorough examination of the head and neck muscles to determine the presence of abnormal tension, and of the external carotid vasculature to determine whether there is an arterial element to the pain.
