Hi Chanell, I too had open heart surgery and I am now into my 7th month of recovery. I have gone through a range of pain and discomfort from the surgery but it has gotten better with time. I still have some discomfort in my chest from time to time and it comes on with certain things that I do, Like climbing a hill during my walk. I believe that yours will get better with time, your rib cage is still healing and trying to knit back together after being pulled apart. Your doctor gave you meds for pain right? Try taking them for the pain and see if it helps. If you have anymore questions, let me know
Take Care, Mandee
