Hi,
6 months and 10 days passed until finally I jumped again, yesterday!
It's been like coming home.
I had no problem at all, complete motility in free fall, no pain during deployment (furthermore I jumped twice but opened three times since I had a reserve ride during the second jump! welcome back!)
Healing meant eating humble pie, I'm stronger now.
Thanks Bigun for your pillow hint, helpful one.
I still do my breathing exercises to strengthen my diaphragm, I've some slight aches doing sit ups or pull ups but that's trivial and they are useful as weather forecast.
Also I could save while not jumping so I just ordered my own rig!
Thanks for your answers.
Gioele
