Rey,

Welcome to Kickas

We had a thread going on this a while ago - have a look at https://www.kickas.org/cgi-bin/w3t/showflat.pl?Cat=&Board=support1&Number=30725&page=&view=&sb=&o=&vc=1

Also if you do a search under ribs or chest you'll find more - in summary quite a few of us have got some form of fusion partial or otherwise that has led to restricted chest expansion, me included.

I doesn't stop me from playing tennis 3 times a week competitively!

Cheers
Jo
