Hello, 7 Months Ago I Had A Serious Heart Attack

Hello, 7 months ago I had a serious heart attack and coded twice. CPR was conducted, and I have had problems with pains in my chest to this day. The best way I can describe it is like the cartilage connecting several of my ribs to the stirnum is broken. I shouldn't complain for the simple fact that I still can, however I was wondering if there are any braces I can wear to aid in healing. I suffer from bad sinuses which cause me to cough quite often. When I do, I can feel these joints flexing, popping, and sometimes they feel like they have came out of joint and I need to shift around to get them to pop back in to place. Thanks in advance for any suggestions. #happytobefeelingthepain!
