Hello, I am an 18 year old female. I had only had a couple of headaches in my entire life until just over 6 months ago. I began having headaches at least once a day from that day forward. All of my blood tests are coming back normal but my scans showed that I had a sinus infection. I was put on medication for the sinus infection and became ill with C-Diff. from the antibiotics. I have continued to have these "sinus" headaches up to several time a day. They are usually accompanied by knee pain, toothaches, ear and nose pain, a runny nose, light sensitivity, skin pain, and nausea. I also have a strange "under the skin" itch, usually in my knees when they hurt. When I get up (even slowly) from bending over I feel like I'm going to pass out. I had a holter monitor because I felt as though I was having palpitations, but the results came back normal. I am also thirsty almost all the time. My only other health problem is a potassium deficiency and anxiety disorder, though both are under control thanks to medication. I'm not sure if the headaches are related to my other symptoms, but I felt the need to share then just in case.
Thank you for all of your help.
