I've done 3 tandems so far and have been thinking about doing my AFF for a couple years, finally wanted to make it happen this year. Found out recently I have a large liver hemangioma (non cancerous liver tumor) that probably won't ever bother me, but I was advised by the doctor not to play any contact sports due to the trauma that might rupture it. How much of an impact is chute shock and landing? I was SO ready for it too, mentally and even financially. I've watched tons of videos and read up lots on the sport. I could have the tumor removed, though it's not a simple operation and the recovery is long.
