As you are experiencing symptoms we do recommend that you get tested (see When to test). The burning sensation you have noticed may be psychosomatic but it is a change so testing is a good idea.
You also said that you have mild to moderate anxiety so you may like to check out our page on “Worry and anxiety”.
