Hi Sarah~ I've had shingles and I agree w/FG; you'll know if it's a possiblity. I first thought I had a cracked rib, as the pain was unbearable. I had a crusty raised rash on my ribcage that was huge.

This was 33 yrs ago, right after I got married. The pain lasted for months. Now they have better meds for it. Like FG said~ it's extremely painful as it's nerve endings involved. Good luck.
