I feel like someone punched me in the upper back between the shoulder blades.  No outside marks.  Still bothering me 5 days after starting.  Sort of feel like my "heart is in my throat".  I'm 47, female, overweight.  Had an endometrial ablation one month ago and strep throat one week later that was treated with antibiotics.
Hi, According to me you have rhomboids and trapezius muscle spasm. Use moist heat over the area for 15 minutes thrice a day. Also start with upper and middle back exercises. Improve your posture and do not watch TV for a long time. Also minimise reading and use of mobiles and laptops.
