Thank you for your question. Although without being able to examine her I can not offer you the specific advice on diagnosis and treatment that she needs, but I would try to provide you some relevant information about her health concern.
Generally, any throbbing headache needs to be evaluated for migraine, cluster & tension headache. One sided headache that is throbbing in nature with dizziness/nausea symptoms could be suggestive of migraine. In addition to that, one sided weakness should be evaluated of underlying neurological disorder that may be the main reason of her bad headaches. The mainstay of the migraine treatment is always to identify the triggering factors and to avoid them. Triggering factors could be different foods such as cheese, chocolate, alcohol and even few fruits. Other factors that may induce your migraine attack may be contraceptive pills, stress or depression, bright lights, loud noise and traveling. Few females experience headache more commonly during the time of their menstrual periods & at the time of hormonal imbalance. I would suggest careful record of events that have proceeded with the attack and avoid those factors. In addition, try to rest in a dark & quiet room, meditate, have a balanced diet and avoid taking unnecessary drugs. Even then if you suffer continuous headache, please arrange an appointment with a neurologist right away who will evaluate the further underlying disorders here that may be the main reasons of your migraine attacks and can provide you an appropriate treatment here. Hope this information proves helpful to you. Take Care & Regards!!!
the next time you go, i would mention checking for hemiplegia, which is a condition that is caused by a stroke or head/back injury. I'm not absolutely sure about this, just thought i would give my opinion.
