Hello, I am new to this forum but I have had health anxiety for the past two years. My worries have mainly been about my brain (aneurysm, tumor, cancer) and heart (irregular heartbeat, cardiac arrest, enlarged heart) but lately it has been over my thyroid gland. I have a minor stationary pain in the left side of my neck that sometimes shoots up to my ear. The pain sometimes switches sides. It's all over the place, really. Sometimes it's in my jaw, or either side of the neck. But I am terrified I have a cancerous tumor in my thyroid and it will metastasize to my brain. I am too afraid to make a doctor appointment just on the off chance that they find something. I feel no lumps in either side of my neck and am constantly checking and feeling around my neck for any changes. I have had these worries for about 3-4 days. Iam sick with worry and don't know what to do anymore. Please help!
