Costochondritis is a severe pain in the chest wall which feels like a heart attack. For me the doxycycline takes it away immediately. It was one of my most severe symptoms with Lyme and it is quite scary as well. If you have antibiotics try taking one when you have an attack.
I remember getting jolted out of bed one night in the middle of the night with this stabbing pain.
