question: a few days ago I was impacted with a hard object just under, right in between my breasts. (esophagus?) the next day and since (on my 4th day) I have had the chills (under blankets in +30 weather doesn t seem right) low energy, headaches, back and neck pain etc. I am 52 yrs old, female, 5.2 , 135 lbs. Should I be concerned I damaged something which would be causing this or would your guess be just a flu bug at the same time. Coincidence? No vomiting but no appetite. No blood in stool.
