I am glad to hear how you are doing @jootzy! It sounds like you are doing really well, especially walking. I found that the more I walked, the better I felt. I feel like I am unrestricted now with walking. I too had the super sensitive scar. It was so sensitive even the softest tee shirts were irritating. I wore V-neck shirts for several months before it calmed down. I hope that happens for you soon too. I am also happy to hear you will be going to rehab. Too bad you have to wait so long though... that's a bummer. It sounds like you will breeze through it. The arm machines were what helped me the most, but all the equipment was helpful...and I met some really nice people there too. Having a sensitive or irritable scar is probably normal, and part of the program in open heart surgery. It just takes time, and we all heal differently. What surprised you the most about going through this surgery?
