I had a bad cough which I thought was left over from a lung infection 2 weeks previously. Then I started getting this stabbing pain in the right hand side of my chest. I assumed it was pulled muscles from the cough. Then the pain escalated until I was almost in tears. I couldn't move without excruciating pain in my chest. My doctor was away and I didn't want to go to the hospital to sit for hours. I had some Tylenol #2's left over from some previous affliction and took those along with Motrin and ice packs. I slept sitting up in a lazy boy. Still figuring it was muscle related I went to my chiropractor. He thought it might be associated with my ribs. He did a body massage with a machine which helps for a few hours. I was still in massive pain. I asked him if I could have a lung infection and he said it was certainly possible. I finally went to my Doctor and it took him a couple of minutes to diagnose pleurisy. That was a week later and way too much pain.
