So I've been struggling with a variety of symptoms for the last 6 months. I've gone to many doctors none found an issue.

Symptoms:

-Fatigue

-shortness of breath

-Wooziness

-Dark blue fingernails and toenails

-Waking up with headaches

Doctors I visited in the past 6 months (they found nothing wrong):

-2 cardiologists

-pulmonologist

-gastroenterologist

-psychiatrist who prescribed some drugs but they didn't help me the least



I am a 19 years old male. 20 in June. I am 187 centimeters tall. and I weigh 65 kilograms.

I thank you in advance for trying to help me.
