TKR

Once they start to come off they start to break up, and you can flick the bits off, it doesn't hurt so much then.

I wish I could remember what my PT suggested I use. It was in India, but it was a legit cream - though it wasn't a cream, it was very light. It was clear and just a little thicker than water. I applied it to the scab. It moisturized and aided in the healing process. I've tried searching and can't find anything. It was Aqua or Hydra something, I'm almost positive...but that was late 2014, a lot has happened since then and I just can't recall. But perhaps you can ask a pharmacist or your doctor. It helped soften it. Did you try the recommendation of wrapping it in food grade plastic wrap or a silk scarf? I have never done that but have heard it being successful for others. Hang in there, it will get better!

Chris, I recommend cold therapy.  Though you say even the slightest touch of any fabric is unbearable, you need cold on it.  Pain is a clear indication of inflammation/swelling.  Just because your doctor has increased your pain killers does not mean you should be increasing your physical activity.  By doing more physical activity, you are going to cause more pain and problems.  You need to heal before you push yourself.

Thank you guys 

Wrap the knee loosely with an ACE bandage.  It prevents rubbing against clothing during the day and the sheets at night.

I used unscented plain Vit E cream and massaged knee and scar from beginning I believe it makes a huge difference, it's early days, keep the faith  it will come right Cheers

I found this jell called BioFreeze...VERY cold once it's massaged in.  Apply and wrap with an ACE or knee sleeve before bed. Ahhhhhh......  Note: Wash your hands well after application.

I use Bio-Oil....thank goodness I never had any scabs...don't pull them off though!! Nature's protection!
