Neurological issues and systematic issues

24 years old Male No smoking, drinking history

Please help me, I have unexplained issues for 2 months.

Issues started with coordination issues at first that i noticed while exercising. Then i also developed brain fog, tinnitus, sound sensetivity. I then developed muscle twitching all over my body and weak legs, that gets worse while walking. I also have aches in my joints, both of my heels and lately throbbing pain in my tailbone and my left hip that keeps me awake at night. I have bad fatigue as well, which is as bad as flu fatigue. My sleep isnt helping me as well, i get tired 3h after I wake up. I think I'm dying. When I try to walk for a few miles my left eye goes blurry and i get really bad confusion episode with dizziness. I also have pretty high resting heart rate, even while sleeping. When i walk, sometimes it gets really bad.

Crazy thing is that i already did so many tests, including whole blood panel, hormones, tumor markers, MRI of head, whole spine, chest and lungs and abdominal mri, colonoscopy and gastroscopy, ultrasound of neck and abdomen and testes. There was nothing really abnormal in all tests, except mild lymphopenia and nothing else seen on MRIs. One thing to mention is before my issues started I got a blow to my face with a ball from a close range. Im a goalkeeper and usually have no problems with it, so im not sure if that could have cause so many issues, especially joint pain and aches.

I can't live my life anymore, I dont understand whats wrong. No one believes me and everyone is saying that I have anxiety. But from what? I just suddenly developed anxiety 2 months ago over night? It's getting stressful and I am not sure how long can I take this, since it seems like Its not getting better. Other docs gave up and not sure what to do. I wanna get my life back! Please help me. 😔🙏
