My advice to all you young headache sufferers: keep trying to get help. Insist on being heard. Persist in telling the docs that your symptoms are ruining your life. Head pain and other head symptoms are a medical jungle, and many docs are lost in that tangled mess.
Head pain, pressure, dizziness, grogginess, burning, muddled thought, allergies, and muscle tension have ruled my life for over a half century. My condition is still undiagnosed, and I'm still trying to get real help.
Eventually you will be too tired and beaten down to fight it. Alcohol and illegal drugs are tempting. And try to get help for anxiety & depression while all of this is going on.
