Welcome to this forum from me and please go to my profile for my pen picture.
I resumed playing Golf, a full round, 4 days after LDR procedure in April 2010.
Your mention of 'strenuous' could perhaps infer that you may be a little over ambitious
to resume normal sporting activities so how about a gentle reintroduction after two weeks
or so. I am certain that your body will dictate how you go about things so my advice to you
is to have no preconceptions and slowly resume your very physical chosen sport at a very
gentle canter. Slowly slowly catchee racketball.
Best wishes with your sporting interests.
