It sounds like muscle strain, have you been doing strenuous activities like lifting? Have

You been to your GP?

Not to much but I do carry around my two year old and my 10 month old. I am 37 and have had 4 kids in 6 years. The ache is in between my blades and brae line. Have been to GP took blood work all looked good

No, I would go to seek your gp.
