Neurological symptoms and diarrhea

I don’t know what to do anymore, I thought maybe if there is someone out there who’s going through something similar it could help posting and asking…I’ve had a feeling of weakness and dizziness off and on since July. In august I was ok. Then in September I had random sensations off and on but daily on my left foot, leg and hand. I also have been having diarrhea pretty much daily. Sometimes less liquid but looks undigested. I also get sensation of muscle weakness but my limbs work fine. No paralysis, numbness. More recently the sensation in my leg became a buzzing sensation in my left foot off and on. Nothing stays it all comes and goes but it’s there every day. I’ve also had a left itchy shoulder off and on. I have also felt some symptoms on my right leg, more like a weak feeling in my leg but still works fine. I do get the weakness sensations in my hands too off and on. Some days better than others. I have a black floater in my left eye off and on. The doctors say that’s normal. Eye exam normal. Head mri normal and a lot of bloodwork normal, including anti inflammatory markers and autoimmune markers. I’m pretty sure many people around me think it’s anxiety but this is different and lasting more than a month now and the diarrhea has me concerned. I don’t have stomach aches it just happens. I’m waiting for a neurology consult but worried it will all be brushed off since all the tests so far are normal. I have the option of doing a spine mri but it will cost me a few thousand dollars. It’s bizarre though, I figured If something wrong with a specific area of my spine the symptoms wouldn’t be migratory like that. Different areas of the spine control different limbs and parts. It feels like it’s a sensory issue but the weakness feeling seems muscular as well? Thank you anyone for any advice or ideas
