Hello Dollymaz, I have only recently joined the forum myself however I have been a regular viewer of the posts but felt I needed to join after the problems encountered with my mother. She is the PD sufferer and I am her carer along with my dad.
Unfortunately this is a very personal disease and everyone's experience is different. I have worked as a secretary in the NHS for over 24 years in orthopaedics however since my mothers diagnosis we have recently moved offices and I am now working across the corridor to my mothers PD consultant so have regular little discussions with him regarding my mums problems. During these conversations and planned consultations it comes across to me that everyone is so different that even the consultants are at a loss sometimes as to what course of action to take, unlike orthopaedics where there is a specific problem and an op or course of therapy that would sort out the problem. Even with my access I feel that there is no straight forward answer to the multitude of problems my mum has, however she does have several other medical problems as well as the PD so the actual cause is very difficult to workout.
it seems to me that you need to try and gain as much information as you can from here, or other trusted sources yourself, regarding your specific problems, and discuss them with your PD consultant.
unfortunately my mum hasn't been on any of the meds that you have mentioned however I am sure that once you see your Consultant he/she will be able to advise you on the best course of action. Maybe someone on here will be able to give you some more advice regarding your specific problems and the meds you are on, however my mum does suffer from neck stiffness and pain.
Good luck with your appt - I would always telephone them to see if it can be brought forward or if you could be put on a cancellation list, if you are available at short notice. If it is your first appt with the PD consultant March seems a long time away to me.
