Im sorry to hear about your symptoms. These symptoms are NOT an indication of anything sinister, simply because you have undergone a complete examination at your doctors office. All of these symptoms point towards anxiety as being the cause of your symptoms more than anything else. Now if there was a brain tumor it would cause headaches along with other symptoms like weakness or numbness in the limbs, blurring of vision, difficulty speaking etc. Secondly headaches of brain tumors can wake you from sleep and can occur early in the morning.. Since you dont have these symptoms it is unlikely that these symptoms can be due to a brain tumor. The tightness can however be an indication of tension headaches which can present in this manner. This would be treated with simple painkillers. Sinusitis can also cause these symptoms as well as antibiotics should help in clearing that up easily. If that doesnt work, then sinus lavages would be helpful as well.
The spot which is tender on your head could be a small infection like folliculitis in which the hair follicle can be infected with bacteria. This can be diagnosed on a clinical examination and then treated with the help of antibiotics which you are already on. Try relaxation techniques and see if that helps, behavioural therapy can also be helpful.
So in summary this sounds like a combination of sinusitis and tension headaches, with anxiety playing a role in worsening the symptoms. This isnt anything sinister from the sounds of things.
