I'm 39 years old and 4 days ago had a heavy fall from a skateboard while messing around with my kids. My left rib cage seemed to turn into my abdomen as I landed and have been in a lot of pain since. Its a dull pain unlike the sharp one you get when damaging ribs and anyhow, the pain really does feel like it is coming from the inside. Is this most likely muscle damage?
Thanks in advance
