Hey @CathyMac I absolutely hear you. I had my single mast in Oct and it took me a good 6 or 7 weeks until I started to feel comfortable and coped with all of my exercises. Now I feel good but I really thought because it was so tight and right back to the chest wall I would never be able to raise my arm high or hold it there. It will come good. It has only been the last 4 weeks that I can now sleep on that side as well. I was told to massage my scar as much as I can to keep the inside of the scar to adhering to the chest wall and this I found hard but did it gently. I was also told to have the hyperfix on the length of my scar for up to 4 months as it helps the scar. Good luck with it all and just be patient with yourself . Big hugs xox
