Hello @meenakshi and welcome to the Parkinson's support group on Mayo Connect. Restlessness and Parkinson's are a difficult combination for sure. As you said you have been taking 200 mg four times a day, I'm thinking that you are taking Carbidopa/Levodopa. Is that correct? There can be a problem called, Dyskinesia, that sometimes occurs after taking this medication over a prolonged period of time. Here is some information about dyskinesia from the David Phinney website, https://davisphinneyfoundation.org/what-is-parkinsons-disease-dyskinesia/

I would encourage you to read this information and then talk to your doctor to see if he or she feels that this could be the reason for your restlessness.

As you probably know, medication and exercise are both important for Parkinson's. Exercise, combined with medication, helps with many of the symptoms and delaying disability. Physical therapy can be a good way to start and then it is important to follow through with a daily plan. What type of exercise program are you using now?

YouTube has a lot of free exercise videos, that are not overly strenuous, but are very helpful to seniors. Here is a link to some of these videos,

As you can see, a lot of these exercises can be done while seated.

Is your doctor a movement disorder specialist? If not, a referral to this type of specialist may be helpful for you. Movement disorder specialists are neurologists who have special training in disorders like Parkinson's and they may have ideas to help you with the sense of restlessness.

Outside of the restless feeling, what other PD symptoms are the most bothersome now? Is your gait and balance a problem?
