How'd y'all deal with rubbing and blisters

I'm an BKA, got a new socket a few months ago and I've had nothing but issues with it.

From the day I got it, it just hasn't been right, combined with the fact I'm actively trying to lose weight it just doesn't fit. My prosthesist has submitted a request for a new one which, if approved I'm going to really speed up and lose my last 5-10kg of fat I want so hopefully it will last me a while when I get my new one.

In the meantime I'm dealing with a socket that's too large and has been modified all the time to try and fit.

The last modification was two pads on either side of my tibula to take pressure off the base of my stump which worked but I've now got a blister and it's very tender on the outside. I've shaved the pad down a little but it's hard to tell how much to take off as it hurts regardless now.

Unfortunately not wearing it isn't really an option, I've been using blister patches which help but don't let it heal quickly. I was thinking about sports taping it or similar?

I've also started getting deep spots on the base of my stump which is new, my prosthesist says they're pressure spots but they're still popping up since the latest adjustment, they're really deep and solid white spots. When my leg is hot they are much closer to the surface but when it's cool you can hardly see them. Any tips or tricks for these?

Cheers guys!

TLDR: solutions for blisters and still wearing your prosthetic, weird white spots on the base of the stump. Please advise.
