Hi,
Welcome to the PD board. A second opinion is what you want to get and if the two differ, maybe a third opinion would be necessary.
Only you can say when to start medication. Learn as much as you can about the disease and the different medications. There is tons of info on the internet.
As far as the right meds for you, again, only you can decide. I was put on Requip at first and it did nothing for me. I did not notice any improvement in 8 weeks of it. So, I asked the Dr. to put me on Sinemet, and that made all the difference. Granted, several years later it does not work as well as at first. I did not take meds or get an official diagnosis until I had PD for about 7 years (looking back I could tell when it started). I didn't have a tremor, so who thought PD?? my symptoms started (looking back) to losing my sense of smell, "dragging/limping" my left foot, could not walk as far, fatigue, then not swinging my left arm when I walked and leaning forward like a hunchback. Thought maybe it might have been from a small stroke. I went from walking 4 miles a day before PD to not being able to go around the block. I felt so stiff and heavy I felt like I had a suit of armour on. Anyway, the Sinemet took all that away but now it is not working as well.
I think you will have to try different meds to find out which works best for you. Everyone is different and not everyone can take the same dosage. If you don't feel bad enough to start taking meds yet, I would wait as long as I could before taking anything. There is not rush to jump into something... PD is a slow progress disease. I started having it when I was about 54 and have had it for 10 years now. Exercise is ultra important. I find water aerobics the best!
Let us know how your second opinion came out and if you decided to start meds.
