It's pretty frustrating. I'm a specialist, but I spend most of my time removing diagnoses and taking people off meds they got started on that they don't need. There are also times when certain meds *do* help with the condition that you're trying to treat, but the side effects totally aren't worth it.
I ran into this sort of thing personally. I started having trouble driving, especially when stuck in traffic. Heart started racing, couldn't see well. No history of anxiety, but I assumed this might be a weird presentation of that - like atypical panic attack. But then it started carrying over outside of driving, and I still wasn't having anxiety, but I wasn't able to walk straight sometimes. My eyes couldn't look at computers for long. Was having some additional visual symptoms. Anyway, had a few ED visits where dangerous stuff was ruled out. Also got admitted and no evidence of MS, seizures, etc. Spent tons of time seeing opthalmologists and neurologists. Everything is coming back normal, so they just start diagnosing me with all sorts of stuff and throwing meds at me. For me, as a doctor, it was a bit bizarre. I didn't want to be a difficult patient and I went along with trying what they suggested, but after the fourth migraine med did nothing (and I'd never had headaches to begin with but they thought it might be basilar migraines), I finally just told them it wasn't helping and to stop everything.
Anyway, I was getting by, but still feeling pretty rough, but then my wife started getting sick too, but only when she rode in my car. That made me take the car to get checked out. They spent all day on it and were really confused, but called me later and realized that some big 17ing plastic bag got caught on my catalytic converter and was melting every time the car heated up and was sending fumes into car, which were worse when the car was sitting still in traffic. They cleaned it out and haven't had issues since (1.5 years now after 12 months straight of feeling awful), but it sure made applying for life insurance a pain in the ***
