Thank you for posting question
I am a neurologist
Let me tell you that a given medical symptom can be due to various causes and the aim of treating doctor is to identify the exact cause and deal accordingly.
Headache can be due to various causes and it can be due to migraine
, sinus infection
, brain tumor
, problem in the blood vessel of the brain. It is also important to note that headache can be due to medicines too. Phentaramine, one medicine which your husband taking can cause headache as well as high blood pressure
. However it can still be due to other causes. I advise you to undergo a medical checkup and the physician will examine you to find out the exact need for the phenteramine. One possibility is that stopping this medicine gradually can make him okky. But still i advise him to undergo a medical checkup so that we should not miss other causes which can these symptoms as i have discussed above.
Hope this help you and guide you for a better health
