@robbiet Hello and welcome to Connect. I know from my own experience that temperature sensitivity happens from nerve irritation. I have that issue with my teeth and I have exposed roots from recession, but it also happened from tight jaw muscles after bracing from dental work because it was irritating the nerve as it ran through the jaw. After I massaged out my jaw relieving some pressure, I was able to relieve some of the sensitivity to warm water. Last summer I broke my ankle, and after the cast was off and I was starting to walk again, my foot was cold sensitive, so when I stood barefoot on the tile, one foot felt the floor as much colder than the other foot. Another example was after I had a spine injection that caused a problem with sharp pains (which was nerve irritation) that hand was cold sensitive for over a year. I am a spine surgery patient, and that was done as a diagnostic test before I came to Mayo for treatment.

I do sometimes uses a nasal rinse bottle with saline to wash my sinuses. That helps relieve some allergy symptoms. That may help if you live in a dry climate and your nose is dry inside. I have asthma and I am sensitive to breathing in cold air during the winter, and even exercise can be an issue.

Have your doctors tested you for allergies? There may be a lot more humidity outside than inside. Do you think dry air may be causing your symptoms?

Hi Rob, I add my welcome. You'll notice that I moved your message to this existing discussion called "Too much cold air entering the nostrils." I did this so you can connect with others experience similar issues, like @nrd1 @bride @joannap @du6721 as well as @jenniferhunter. I encourage to read through the past posts to learn what others have shared.

@robbiet-Hi. There are many things that can cause these sensations. I encourage you to read through the replies. As well as ask your provider to educate you on the why’s and how’s.

@jenniferhunter mentioned accurate points about the nerves, allergies and climate.

The nose is a highly sensitive, subjective place changing all day long in response to internal/environmental/emotional stimuli.

Be very thorough in explaining any changes in your environment, medications, activity level, food changes, stress level.

I will list some examples that can cause these types of sensations;

-dry climate (restriction of ciliary beat frequency)
-frequent climate/elevational changes
-allergies
-new work/home environment (lack of humidity)
-Vitamin deficiency’s (D, C,B12)
-breathing rate (shallow fast breather vs. slow controlled)
-blood pressure
-sedentary lifestyle
-medications that dry/constrict blood vessels.

humidification/hydration/inhalation of
peppermint oils can all change/calm/soothe the sensitivities .

•Notice everything listed is derived from your own autonomic nervous system sensitivities. The skin inside your nose is a vital organ just like the skin you have on other areas. If you have sensitivities to other things on your skin, chances are you would have sensitivities in your nose as well.

These are just some. Keep track of when you feel this and be very detailed when speaking to your provider. Ask them to explain the role in the autonomic nervous system and the nose.
