Is parkour dangerous

I've done park our since I've been 17 I am 21 now... Since I've started I've gotten two herniated back disks a shattered talus a broken wrist and my fare share of cuts and bruises. This last fall I had which has shattered my talus may keep me off sports the rest of my life. In the end Parkour has it's dangers if you do decide to do it acknowledge your limits go about it patiently with time and know you do have limits.
