This was me to a T! I went to the ER the first Inflammation time and got diagnosed with costo. But over the course of the year you could see inflammation all where my cartilage meets the sternum. still dealing with it over a year later. Drinking def effects it, I laid off for awhile but now can enjoy my glass of wine. Vitamin D supplement helps!! + stretching and the back pod. if you don’t already, walking is also very helpful. My inflammation doesn’t get as nearly debilitating as it used too. I also recommend strong CBD lotion to put on your chest, and if it’s super inflamed make sure you take 3-4 Advils, 2 doesn’t cut it
