Dear Barbara, It is possible for lithium to increase PD symptoms, and no doubt your physician is waiting to determine whether you will benefit or not; I believe you should call him/her immediately and describe the new tremors, and the fact that cramping has not diminished. Low levels of calcium, magnesium, and/or potassium can also lead to, or contribute to, cramping. I would be sure that you are getting 1200-1500 mg calcium, 350 mg magnesium, and ample fruits and vegetables (for potassium) daily. Some people have also found that large doses of vitamin E relieve cramping in PD. You need to speak with the physician about this, as the amounts are quite large -- up to 1600 mg/day.
