My Mom has had COPD for a long time and in the last 3 months she has been having chest, shoulder, going down her arm pain also...I was really concerned it maybe a heart issue and she has had several tests all show her heart is in great condition. She says sometimes her left cheek also feels strange and a warm flutter goes all up and down her left side from her toes to her head. Have you been able to get any relief from your pain?
