Yesterday, I noticed a soreness in right upper sternum area. I also had a slight headache. The soreness continued thru the night and today. I went on a tour with friends today. I did a lot of walking and going up stairs. I tired easily and got breathless on stairs. I was the only one in the group to get hot. I sweated a lot underarms and trunk area. Also noticed over the two days a distinct body odor that was very embarrassing. I did not forget my deodorant. Before showering, I couldn t determine where the odor was occurring.
