I've had an ache sensation in my throat , ears and jaw, me dr told me earlier on in the year that this was stress related, I noticed today a dark red patch on the roof of my mouth on the left st the back, the inside of my nose also stings. I have been under a huge amount of stress for a number of months. I have also within 3 weeks, started a diet and lost 10 pounds. The aching does come and go.
