Young Onset Parkinson's

I have some symptoms of Parkinson's, namely muscle rigidity in fingers/hands, and jaw, loss of fine motor skills, joint pains in fingers/hands/arms, some loss of facial expressiveness, and slight off and on tremor in both hands (although I've read that tremor is often not present at first in Young Onset cases) I am taking a small dose of a medication (Seroquel) that can, in very large doses, cause drug induced Parkinsonism, but have been assured by my GP that it would take 10 times higher dose and even then is very rare. I have no insurance and no way can I afford to see a neurologist.
