The letter from the hospital says I have Parkinson of unknown cause, the letter also says he’s worried about Multiple System atrophy. So not sure what to make of it all, Google has lots of scary stuff 
which I’m not sure if I believe or not.
Hi WestCountryNordic,
Welcome to our community forum. Over time you will hear from our members on the subject of MSA, but we can also point you here: Types of Parkinson's | Parkinson's UK. You may wish to start here and explore our website for more information – although as our community members often say, too much information can be as bad as too little. Take it slowly and don’t let the amount of data overwhelm you. Also please feel welcomed to reach out to our free and confidential helpline, on 0808 800 0303, as our advisors are always happy to answer any questions you may have.
With our warmest welcome,
