Nodules after noninvasive fat destruction is common. I would recommend that you wait until the nodules are gone before starting your next treatment. Keep drinking water and massaging the area and that should help speed the recovery.
After any neurotoxin injection lines can form for any muscles that are not paralyzed. Some muscles do start to overcompensate for the ones that are paralyzed. If you see this starting to happen then you may want to inject more to get a full and even response in the area where you are not wanting wrinkles.
I have not had any burns from SculpSure but the inflammatory response can take time to resolve. You should notify your provider about these concerns so these events can be investigated. You may need a lower setting on your next treatment and that will help reduce the lumps as well. You sound like you will have a great response from the treatment. Keep your practitioner in the loop for best care!
Yes, you are a great candidate for neurotoxins. You just need to work closely with your injector. I would do a staged approach to make sure you get the results you want. There is artistry involved and good documentation what what works for you to reproduce the results you want each time is key. Don't give up!
SculpSure does not penetrate deep enough to be a concern with IVC filter. You are good to go! Happy Sculpting!
