Thanks to everyone for the replies. Just wanted to give an update. Had a moment of weakness and used a coat hanger to scratch down in my cast. Long story short there is no longer any cotton padding left inside my cast. Also my leg is about 1/2 the size that it used to be so now the cast is no longer an issue. It’s comfortable now when laying down and I just stuff a soft towel down inside so its not loose when moving around. Have started doing crunches and upper body excercises for the last week or so. Makes me feel a bit better. Leg still doesn’t feel great, I thought it would feel more healed by now. 2 more weeks to go until cast is scheduled to come off.
