My boyfriend has a thumping inside his chest. 80, active, on viagra (sildenafil). Er?

80 years old. If he is 80years old and has chest pain go to er.
Check with his Dr. Seems to be doing very well for an 80-year-old. Should be ok, but should make sure his heart can take it. Decision is his. There may be only a mild risk from viagra (sildenafil) and he may be willing to take the risk in return for pleasure for both of you. Good luck.
