hi I m 25 years old, female. And the last couple of months I have had pain in the back of my neck, back of head, sometimes front front aches and around eyes, pressure in ears, I feel like I have swollen glands on kneck all the time, I can t concentrate, I forget things, lack of energy, I have bloods done for thyroid etc and all came back normal. When I start thinking about it I feel there s something stuck in throat, I feel depressed over this, petrified incase it s a tumour or cancer and i have not got an appointment with doctor for another two weeks. What is the possible cause for this
