Hi,
55 yr old male, smoker for too many years to count, very anxious lately, smoking even more, had tightness / blockage type sensations in centre of chest, doc prescribed Zantac, checked out my chest and back told me lungs were clear, but went for precautionary x-ray, docs tell me nothing on it,, still getting prickly type sensations in upper chest on R H side, not coughing, not out of breath, no wheezw, could it be anxiety / muscle related .!

thanks Bruce xx
