Yes, these symptoms can be related to his treatments. Dizziness is a common side effect of blood pressure medications like telmisartan, especially if his blood pressure drops too low. While aspirin rarely causes leg pain, patients who have had an angioplasty are typically also prescribed cholesterol-lowering medications (statins), which are a frequent cause of muscle pain in both legs. Please do not stop any of his medications, especially aspirin, as this is vital post-angioplasty. Monitor his blood pressure when he feels dizzy, and consult his cardiologist promptly. They can easily adjust his dosages or evaluate the exact cause of his leg pain.
