I can't get properly diagnosed and I'm spiraling

I'm a 32yr old male with no history of anything and never been on any medications either. For a few years now I've been suffering with symptoms that seem to be getting worse as time progresses. I've seen multiple neurologist and rheumatologist. Each one has a different speculation and each one wants to put me on a pill with no straight answer. I refuse medications because each one has bad side effects. I need answers, not pills but that's all every doctor seems to want to do with me. A few years ago I started feeling very small shakes in my legs every once and a while. As time went on it started getting more frequent. I'm at the point now where I feel constant little tremors in my legs daily. Sometimes in my chest and even jaw. I feel it all most when I lay down to try to sleep. I feel extremely weak and tired. My sleep patterns are horrid. And my most recent symptom is driving me crazy. I keep getting a weird sensation that feels like it starts in my head and then shoots an uncomfortable sensation down to my left foot and makes my toe muscle twitch. I'm not feeling pain. Just extreme discomfort. I feel this when I lay down and close my eyes. It's keeping me awake. I have no answers for anything I'm feeling and I'm at a loss with all of this. Can anyone shine some type of light on this? The only thing that came up was Small Fiber Neuropathy when I had a skin biopsy done. But that was it. My primary care physician is saying I need to see a psychiatrist to rule out this being anxiety. I can confirm that this isn't anxiety. Everyone keeps tossing me around due to them not being able to get a proper diagnosis. Every doctor runs some bloodwork, 1 or 2 test and then wants to try out pills without any answers. Then when I deny any medications they say that there is nothing more they can do. Also, if I focus on the sensation, it'll consistently happen and then my body goes into panic mode. In which case I wind up shaking and feeling like I'm having a panic attack.
