You may be having a Hashi's flare or an oral reaction to something. Have you increased your iodine intake recently? Changed your mineral supplements? I know you have changed your eating habits a bit.. have you added any new foods?
It sounds like one of two scenarios to me:
1) You had a sudden spurt of thyroid activity the sent you on a brief bender. Are you still having these issues or are they relaxing somewhat? The brief spurt of hormone could cause irritable bowels, anxiety, swelling of the thyroid.. etc.
2) Mild oral allergic response: swelling of lymph nodes and throught, breathing restriction, digestive tract irritation (irritable bowels), etc.
Did you get a rash, swollen tongue, all over itching? This would point more to allergies..
Adrenal irritation due to stress can cause brief thyroid highs or lows. If you have been under stress.. I KNOW YOU HAVE WITH THE MOVE AND ALL
.. then suddenly that goes away.. your cortisol could have plummeted temporarily allowing for a brief T3 hay day. There are all sorts of scenarios. To rule out thyroid you should get Fts run. How is your heart rate and BP doing?
I hope that you are doing better now.. UGH! Must run the spiced pears are boiling over!
