Post nasal drip, nasal congestion, hormonal problems! Any connection?

Can't guess if there is a connection between nasal problem and abdominal pain. You do say that you had thyroid hormone tests run. Do you have thyroid problem symptoms ?  Did your doctor do a physical abdomen exam? Did he do a liver panel?  

I have seen several posts here from people starting certain thyroid medication having flu like symptoms.

Otherwise, hormone imbalances can result in a depressed immune system. Some people with thyroid disease have anti thyroid antibodies high enough that they need their levels to be at the top of the range to be effective. If you're still having thyroid symptoms, you may need to have your levels on the high en to feel well.

Also, many people with thyroid disease have stomach problems and food sensitivities. Particularly wheat and gluten cause problems for people with thyroid disease.

Dairy can also cause the symptoms you're mentioning as well.

I have terrible post nasal drip which is all in my throat and nose, that makes me feel congested and I have to keep clearing my throat all day.  I asked my endo, and he said that post nasal drip is common with hypothyroidism.  So, I did my research and sure enough there is a connection.  Not sure if this is whats causing your thick musus and nasal congestion, but I though I would mention it, in case it applies to your symptoms.  I found also that post nasal drip sensation can be caused by excessively thick secretions.  So, I see that thick mucus is a part of post nasal drip, which may be what you have?  Not too sure on right side abdominal pains.  It depends on where your pain is, what type of pain, and if it's acute or chronic.  Now that all being said.. you actually never stated if you have hypothyroidism?  You mentioned your thyroid test were normal but never said if it was because your on thyroid meds or not?  So, if you do not have hypothyroidism and are asking if your symptoms could be thyroid related, then I would have to tell you that you would probably have a bunch of other symptoms that are more common with hypothroidism first or together, which can be fatigue, constipation, hairloss, slow heart rate, dry skin, weight gain,  feeling cold all the time, low body temp, puffy face, weakness, depressed mood..ect..  So, if you have some or most of these symptoms, then I would continue to keep looking for thyroid issues and get your thyroid antibodies tested, if they are negative, then it is most likely not thyroid related and you have to look elsewhere, but if they are positive, then you have Hashimoto's.  Best wishes...

I don't have an awful lot to offer in terms of knowledge or advice, just thought I'd chime in on the abdominal pain. My thyroid function was tested recently and was normal, but my antibodies were high. I have suffered Hypothyroid type symptoms for some time. I also used to suffer terrible right side abdominal pain and was diagnosed with a grumbling appendix. Until one day it burst, I had to have it taken out during an open procedure and a week stay in hospital for Peritonitis. Persistent right side abdominal pain should never be ignored. Good luck.
