I want to know the symptoms of having a high cholesterol and what is the best medicine for this. Thank you?

No symptoms--Niacin. There may be no symptoms. However, the safest, cheapest, most effective treatment for high cholesterol is niacin--vitamin b3. Niacin will lower total cholesterol, ldl, and triglycerides, and raise hdl. Only adverse effect is harmless (and transient--about 20 minuutes) flushing and itching, to which you will become accustomed with continued use. Dose required is 1, 500-2, 000 mg per day.
Depends. Most people with an elevated cholesterol have no symptoms for many years. But high cholesterol contributes to the development of coronary artery disease and peripheral vascular disease. Symptoms: chest pain, dyspnea, stroke, heart attack. Treatment: low cholesterol diet, exercise, don't smoke, manage diabetes. Medications: statins (atorvastatin and Rosuvastatin are the most potent).
Change your diet. The best medicine may be a change in diet,if you are willing to slow transition to a vegetarian diet and then possibly to a Vegan Diet (see Checklist on Vegan diet). Studies show that vegetarians, as a group, are much less likely to die of a heart attack than non-vegetarians. And Vegans even less likely than Vegetarians.This same dietary change may also reverse your diabetes. http://bit.ly/1OiIRcI.
