Problems with Radiesse.
You bring up some good points. But, first let me reassure you that your skin should return to normal once the product is gone. I am assuming though that you have seen the doctor who injected the Radiesse and had him/her do a thorough assessment of the problem. It’s important that you follow up with her/him in person and not just on the phone.
These types of problems are one reason I’m not a huge fan of Radiesse. If there is a problem with Juvederm/Restylane (the fillers in the hyaluronic acid group), a bump can be corrected with an injection of a small amount of an enzyme to dissolve it. For more information see my article on Filler Mistakes & How to Fix Them.
If Sculptra is mixed correctly, injected correctly and massaged correctly, bumps are very rare. But, these types of bumps can occur with Sculptra too.
