I had "biogel" shots in my butt about five years ago. How do I know if it spread?

I actually forgot about it because I didn't see much results however recently I have been having discomfort in my hip amd I don't know why. I immediately panicked thinking maybe this mess is spreading. I am still soft in my bottom area with with no discoloration and no type of disfiguration but I am worried that it has possibly spread. What will happen to me if It did? I am not in the financial position to have reconstructive surgery of any kind.
