The pain under your breast could be costochondritis which is an inflammation of the muscles between your ribs. You can use Tibb Rumaflam tablets and Tibb Antiflam. Also massage the affected areas daily with Blackseed oil. Take hot baths instead of showers and place a cup of epsom salts in the water. Try to go for regular massages to relieve some of the tension. Cupping is excellent for releasing muscle inflammation
All the best
