My mother Joyce (71, MSA) is having terrible internal tremors. She's had these off and on, but they are coming on strong a little while after taking her Sinemet dose. She has been on Sinemet for about 3 years now and she hasn't changed the dosage lately. \ Could she all of a sudden be having a reaction to the SInemet? Thanks, Debbie Debbie White [log in to unmask]
