In other words if the benadryl is helping you I would recommend to keep taking it. Chest pain could be caused by a variety of things both cardiac and non-cardiac and if these symptoms continue you should discuss them with your doctor. There are no known long-term side effects from it's use. Hope this helps. Feel free to write back with any additional questions.
