Hi I've been having head pain for a few months. It's starts in the morning and goes all day. It used to be on the right side of my head but now it's alk over. Sometimes I have a stuffed nose when I wake up. It's more of a stuffed heavy head feeling. My neck hurts sometimes also. I just got glasses 2 months ago. Do I have a brain tumor?

Go to a doctor, explain your symptoms and be diagnosed properly. We don't diagnose on AMHD

My head is tender when I touch it in certain spots as well.

Go to the doctor. We cannot diagnose you online.

The chances that you have a sinus congestion that has turned into a bacterial infection that will respond to antibiotics are much, much higher than a brain tumor. So stop thinking the worst until you KNOW! The other most common reason is allergies.
First, go to a drugstore and buy some different decongestants and some Benadryl. Read all the labels to get different ones. Try them for a few days. Meanwhile make an appointment at a clinic if you don't have a doctor, because antibiotics are by prescription only. You can always cancel it if they work.
