Toporal XL lowers the heart rate and blood pressure, maybe your dose needs to be adjusted. Ask your doctor if he can cut back on your dose.
Are you still taking Tropol XL? Are you checking your blood pressure at home three times a day now? Your blood pressure is very low. When the bottom number drops 35 or below, the liver could start failing. If you are having chest pain, go to the emergency room. There must be something going on that they have missed. Usually chest pains mean that there is a clogged artery in the heart. Take care.
Did they tell you to see a cardiologist or see any Dr for followup? If all the tests they ran were normal, but you ovbiously are still symptomatic...more testing needs to be done. I can't tell you that I know exactly what is wrong with you, but can tell you that with unresolved sypmtoms and no diagnosis you need to go back to your Dr who will, hopefully, be able to make the appropriate referral.
Until then be sure to keep yourself well hydrated to control your bp from dropping further.
