I thought I was having a heart attack, however at the hospital l was diagnosed with Cosdrochondritis (chest wall pain) As l am 66 and have had severe/chronic pain with osteoarthritis, I then developed Shingles on my left side chest, about 30cm square and back over shoulder blade and under arm. The Shingles has cleared leaving scaring, however the pressure/pain from the Chest Wall is still with me, how long before this inflammation clears up?
