skin test biopsy used with Parkinson’s diagnosis

[Doneanddone]

I am currently in the process of finding a valid diagnosis for my physical symptoms. In February 2023 I was diagnosed with Parkinson’s, because I did not receive bond continually to the levodopa carbidopa, we are now exploring the diagnosis of Atypical. Parkinson’s with MSA.

I have had a dat scan, blood test to determine if I have a substance that attacks muscles?? CAT scans, MRIs, and still not a diagnosis.

any comments, guidance, suggestions, will be greatly appreciated.
