Update.. finally scheduled for explant in 6 days! Should I get en bloc or total capsulectomy?

This is something that you have to decide with your surgeon based on the severity of your capsular contracture. If the breasts are hard to the touch then you will probably require a total capsulectomy but without examining you personally its difficult to give specific advice. Whether or not you would benefit from a simultaneous lift is also something you'll want to discuss beforehand. Best of luck! 

It sound like you should have the capsule removed as much as possible.  Your pain symptoms may be related, but there has bee no scientific evidence in the literature to support malaise,vision loss, etc. with implants.
