High cholesterol and high Blood Pressure are commonly associated with Hypothyroid ...........this can also cause a burning sensation in the shins etc
I suspect you have low thyroid function that has been overlooked/ignored by Allopaths
see
www.drlowe.com
Also if your water supply is Flouridated or treated with Aluminium salts or alum or you cook in foil or aluminium or non stick coated cookware these can all attack the thyroid and cause arthritic symptoms
When you have checked and eliminated the above then post all of your symptoms etc plus the answers to the questionaire and i am sure someone will have some ideas
