4 hours ago it felt like a rod was inserted through my right chest into my left. Just under my breast. I felt pain where this imaginary rod was for 10 minutes.. Then for next half hour to an hour in my left & centre of my chest. It then moved to between my shoulder blades... It is still there. It s a 35 degree Celsius day (hot) and I was covering myself in a blanket an hour ago now I m feeling rather warm inside but normal On the outside. I can walk around, eat, drink ... With no problem... Lying down my back is rather uncomfortable between the shoulder blades & going straight across that back section I feel inflamed inside. Slight headache coming on. Other than that I m fine??
