What a struggle you have been through! You are being such a trooper about it, taking each challenge in stride. It makes me so mad when health care professionals don't listen to the patient! Thank goodness you finally know what was causing your hives. Your scar and whole leg look really good to me - not red, weepy, or swollen. One thing I liked about being able to see my scar (and the only thing!) is that I could see that bending my knee was not causing the wound to pop open. While it was covered with a bandage, it really felt like that was happening. I can't tell you how much better my second week was than my first week! So welcome to a better week for you too.
p.s.: I have an adjustable frame on my bed, so I've been sleeping with my legs up in the air. This has been good for my leg, but it also helps me resist the temptation to roll over on my side. I wonder if some risers under the foot of your bed would help?
