Hi LP, yes I had it and it is very scary ! There is a condition called costochondritis which often accompanies Lyme. It is a sharp heart attack like pain in the chest wall. Many people end up in the ER thinking they are having a heart attack. May be called by swelling of tissue in the chest wall. I took doxycycline and it stopped the pain immediately. Hope this helps.
