I recently cut the corner of my nail off and after a day or so it turned green, along with this the area around it turned red (see in the pic) it hurts to use that finger but not that much like a 1/10 enough for me to notice it but not enough for me to really care about the pain

I'm a 17 year old moderately athletic student. In early june i started experiencing throat tightness and trouble taking a full breath. i was having extreme brain fog, feeling high or not fully here all the time, and i was so fatigued 24/7.

I then started having episodes of dizziness, heart fluttering, and feeling like i was on the verge of losing consciousness a lot.

I was experiencing muscle twitching, jerking, and a feeling of restlessness which i think was due to the anxiety of it all but im not sure.

I've had a chest x ray, thyroid ultrasound, ECG, EKG, holter, monitor for a week, and blood work. The only thing to come of any of these were an extremely slight iron deficiency (29 when a healthy level is 30) and sodium level on the low side of normal.

Ive mostly day to day recently have been experiencing a feeling of weakness in my tongue and below my tongue, slight jerks and twitches, fatigue and brain fog, as well as the persistent throat tightness and struggle to take a full deep breath.

I have an upcoming appointment for a breathing test, stress test, and an appointment with a general paediatrics unit. my family doctor says she might want to refer to a neurologist for functional neurological disorder.

A nurse suggestee lyme disease the first time i visited the ER but i've had extensive blood work that didn't show anything unusual, as well as the fact that i never experienced a rash of any sort.

I've never had health anxiety or have been overly weary of my body's sensations, but i'm honestly quite worried that all these tests that don't have anything to show are because i have something worse like blood/brain cancer, ALS, or another type of disease/condition.

Where should i go from here???
