Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query The symptoms you have discussed are absolutely in favour of migraine. Migraine is what doctors typically call a Primary Headache. This is a headache wherein no cause is found. I am not talking about triggers. He may have triggers like food items and lack of sleep etc. But there is no cause why the headache has developed. While that means that the tests are normal, eg the CT Scan, it also means there is no absolute secondarily treatable cause. If for example, patient has headache due to sinusitis, we can treat sinusitis and the headache will be gone. This is not possible in migraine There are however medicines that can be given in chronic migraine like pregabalin, some anticonvulsants in low doses, some antipsychotics in low doses. These medicines when taken over a period of time manage to reduce the frequency of headaches. The best way is to obviously identify and avoid the trigger of migraine. triggers are like fast food, coffee, watching tv, loud music, lack of sleep, bright sunlight. Only he can identify his triggers. Once identified, we can help tell him how to avoid them. Right foot swelling is not related to migraine. Suggest testing FBS, TSH if not previously sent I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further.
