Hi, The Past Few Days I Have Been Experiencing A

Hi,

The past few days I have been experiencing a dull ache at the base of my scalp. It does not feel like it is my neck but rather the bottom of my skull on either side of my neck bone. It is waking me up at night, giving me a headache all day that nothing helps releive and is making my eyes sensitive to light. I have tried to ice it and put a heating pad on it. I have done stretches and tried to get extra sleep so as to rest it but nothing seems to help. What could be causing it?

Thank you
Michele
