Had this old injury on my left intercostal somewhere just inferior to my pectoral... Happened when training about 6 months ago, and I gave chest and core a break and rested and it healed up pretty nice.

Had whooping cough for the past month (finally subsided), and heard a pop and had excruciating pain in the same spot on my ribs...

Anyway I can hardly sneeze, get out of bed without pain.. ROM on my left side is limited due to pain...

How long does this take to heal? I really want to train again but not with pain and risk of reinjury!
