First thing in the morning and sometimes when it is almost time to take my next pill I have a shaky feeling even though there are no visible tremors. The feeling of being panicked yet there is no fear. The feeling of shivering from the cold yet being very warm and in fact sweating. My muscles are achy and tight. It feels like there is a giant rubber band around my torso squeezing me. About an hour after I take my pill my muscles start to relax and I get comfortable.
This is how I felt all the time for a long time before I was diagnosed. My doctor was very sure it was because of my depression. It wasn't until I actually started hand and jaw tremors that my doctor would consider anything other than depression. All the while my balance is getting worse, my fatigue is greatly limiting what I can do, and I have signs of dementia.
Many people think that Parkinson's is just a shaking disease. They just don't understand that it is a debilitating disease.
