parkinsons mis diagnosed

I was diagnosed with Parkinson in January of this year 2022 and my consultant put me on tablets as i had low dopamine on the right side of my brain only (results of a DAT scan i had in October 2021)
My shakings of my legs was causing me problems when i was standing or walking on them as i sat down the shaking was worse, about 3 months ago my consultant told me i don’t have Parkinson but tremors as i got pains in my legs and knees she has referred me to a rheumatologist, It was diagnosed as stated in January then told to now told to stop taking my medication which why i was diagnosed and then told i did not have it it has confused me there is a lot more to this but has anyone else had the same problem, thanks
