Dessicated Thyroid Isn't for Everyone

My immune system has gone bonkers since I got the bivalent Moderna booster on September 23.  I have heard of people having strong vaccine reactions after having had Covid, and unfortunately, I seem to have joined the crowd.  I had Covid in July, and I believe my immune system has gone into overdrive in an attempt to destroy the vaccine.  The upside is that I should now have very strong protection from getting Covid.  

I've been dealing with hives and the most intense itching ever.  I have memory problems and a poor mental attitude, the likes of which I typically see in a strong autoimmune flare.  The problem is that I'm not exactly flaring, at least not in a normal fashion.  I feel certain that this is from the vaccine.

My thyroid levels have been unseated from where they stayed for three years, and I have an upcoming appointment where options will be discussed.  I think my current medication, NP Thyroid, causes the hives due to it being derived from desiccated thyroid.  I'm considering asking for a complete switch in medication, which will completely screw my body up for 2 to 2 1/2 months.

I explained in an old post what happens when thyroid medication is either increased or when a patient switches brands.

I am four days in and feel better than I did on Monday; however, I can tell that how I feel has just started to deteriorate.  I always feel better for most of the first week, then the drop begins.  I can feel the very beginning of the drop coming on.

This happens because the hypothalamus detects the sudden increase in thyroid hormone in the body due to the medication increase.  The hypothalamus then secretes a hormone that tells the pituitary gland to shut down the thyroid, which then makes the patient feel sick for two to five weeks or possibly even longer.  The lengthy adjustment period is caused by the long half-life of T4.  It takes weeks for the hormone to stabilize, which is why many thyroid patients feel bad for a lengthy period of time after any medication change.

I have until December 5 to decide for sure, but I will likely request a change, thus beginning the horrible adjustment process.  This is why I have put up with the itching, which has not been bad for much of the time.  It's just that the itching is now so out of control that I'm about to lose my mind.  I'll take the deep fatigue and muscle aches instead, please.

I'm open about sharing this information because my experiences are not the ones that are prevalent in online groups.  Everyone online believes that desiccated thyroid is the only good thyroid medication and that nothing else works.  It appears to have given me hives off and on for years.  Not everyone gets on desiccated thyroid and has a perfect life.
