hi cynthia,thanks for query.Chest tightness
could be due to muscular spasm or indigestion
can aggravate the symptoms and lead to increase frequency of attacks.Please avoid getting anxious,take light diet,avoid high fat foods and cold drinks.Watch your weight,do regular exercise.You can apply any local analgesic
that you are comfortable with.this should help if not please visit your doctor for examination.
wishing good health.
