Dealing with rude drs

So Ive been diagnosed with two types of TBI’s by 3 different drs…

However I recently went to a nuero who was extremely rude proceeded to tell me I “couldn’t have a TBI because I’m not in a coma” and told me all of my symptoms are from a “really bad headache”

Some of my symptoms include extreme nausea , can’t be around light or loud sound without extreme pain, can’t fully read and process what’s going on around me , my left side doesn’t function , and more

He was so rude and unprofessional my husband / caretaker had to step in and explain my day to day life because he kept talking over me..

Now usually I’d say just to find another neuro and move on but it took me from may 21st 2025 until April 2026 to even get in to see him.. he’s prescribing my migraine meds which I need to even get out of bed most days and I don’t know how to deal with him .. I tried to switch providers but they won’t let me and idk what to do… if anyone has any advice please let me know ..
