Headache and ear pressure since months.

Hello Doc ,I am suffering from headache on top of head(parietal region) and also pressure in ears since 3 months now. Headache comes and goes  mild in nature but disturbs my daily activities. Even when i put my hand in hairs it triggers the headache. Its less in morning but as the day passes by it intensifies and by evening even  forehead starts paining. I thought jts ear problem so showed to ENT but ear pressure was normal. Also i am suffering from severe hairfall and frequent mild numbness in hands when i put pressure on it since 10-15 days now. In september i had gone for brain CT scan which came out clean.Went for blood reports and ECG in Feb that was also normal except for bit sinus trachycardia.Even when i put on earphones ear and head starts paining. Past 1 years had been very stressful for me and also i sit on phone and computer a lot in whole day. what can be problem for all my symptoms? Is it Vitamin deficiency problem or something serious such as brain tumor or anerysm?
