Chest pain, hard breathing, pain of right arm because of tennis elbow reaching to neck & going down to shoulder & upper back.what is this&what can i do?

See below:: See an orthopod for the arm/shoulder pain and your gp for the chest pain, difficulty in breathing. The arm sounds more like cubital t syndrome which is known to move towards the shoulder or chest/ upper back. It does not happen with tennis elbow. You could have both though. Do you have RA as you are on enbrel (etanercept)? Why are you taking inh (? Tb)? So maybe a chest physician referral maybe helpful.
