Hi, Its suggestive of side effect of Concordat 5. Concord 5 MG is commonly used to treat high blood pressure and other heart diseases. Its most common side effects include low blood pressure, decreased heart beats, flushing, fatigue, muscle pain and impotency. Consult your treating doctor for a possible dose reduction of Concordat or an effective alternate but a safer Chat Doctor.  Vitamin E or D is unlikely to cause muscle pain. Hope I have answered your question. Let me know if I can assist you further.
