The reason is you are taking a combination of Foretell+Budesonide where foretell is a bronchodilator and budesonide is a steroid. The problem you have is due to Foretell and the common side effects are headache;tremors;FM like symptoms;dizziness;palpitations;increase in heart and pulse rate;nausea;muscle cramps etc. Please consult your doctor, and he may either reduce the dose or shift to some other medicine. Thanks </s>
