I am a 31 year old with very similar symptoms. I feel like the front of my neck is going to explode at times. I DO have an autoimmune disorder, lupus. Mayo confirmed my blood work to be clear of lupus at the time being (this past week actually). Autoimmune disorders behave this way, as well as premenopausal and menopausal symptoms. If your doctors aren't satisfying you, and just pushing pulls at you left and right that you aren't tolerating, FIND NEW DOCTORS. medications are not always the answer. Remember this as you seek treatment, my local doctors have almost killed me 3 times now treating me like a lab rat. PRAY. and be patient. Definitely have your blood tested for autoimmune disorders, as well as hormone levels. Have them check your pituitary gland as well (MRI). Some times little annoying growths (NOT CANCER) will cause these annoying problems. If all else fails, Mayo in Rochester, MN is awesome. They can help. Try and control your fear and anxiety when these episodes occur, as it only makes things way worse... STAY CALM. If all else fails, go on Mayo's website and request an appointment. Best wishes for you. You will be in my prayers.
