Hey I think for 6 weeks post op you are doing great!!!!!!!!!!! The only negative to sleeping on your side after abdominal surgery is the extra pressure on the site especially if your bloated. The numbness is the nerves that are also cut, some will reconnect some wont but that takes up to a year. I have had two major abdominal surgeries and alot of the sensations came back just weird feeling even the texture of the skin is different in the areas that didnt come totally back. Keep getting better.......
