2 surgery and now one side is caved in. Is a 3rd surgery too risky? Major regrets.

I had 2 rhinoplastys that I shouldn't have had. I thought my nose was too bulbous, so I had a finesse tip rhino in 2014. 6 months after my surgeon did a revision to remove a bump that had formed on the bridge ( it was only small). Since then it's been a disaster. I noticed a dent in the left side and so he put a temporary filler. Now the tip looks like it's caving in too on that one side. Can this be fixed? Is it too greater risk to have a 3rd surgery? It's been 17 months since my last operation.
