In reply to JForonda:
Hi, not sure if I can give you medical advice but I certainly empathize and hopefully can give you some reassurance as I also had a spontaneous pneumothorax when I was in my early twenties.
It did take a while to recover from the phycological effects rather than the physical of such a huge episode- I thought I was super fit climbing hard and regularly, running and cycling ect then bang! For about a year I worried everytime I got out of breath and was anxious to really push myself physically but eventually this pasted and within 18 months I was certainly climbing far beyond my previous pre lung collapse grade.
Take it easy and when to feel confident and fit enough get out and walk you'll soon be climbing again although 'm not sure climbing in a chalk filled environment would be too helpful initially but as I said earlier the sooner you get back to your old self and get your head around what's happened the quicker the rehab.
I hope that helps and the very best wishes for your recovery.
Regards
Jim
