Since you already suffer from asthma, acid reflux
and musculoskeletal pain
, i`ll attribute it to these conditions. However, costochondritis
is also a possibility. You have to ensure that your asthma and acid reflux are well controlled. If despite adequate treatment for these conditions pain persists, take a analgesic
like tyelenol and apply local heat and a analgesic gel. When you visit your pulmonologist discuss it with him.
