My son is 15 and has your same symptoms. He has ADHD, anxiety, a heart defect, and had Covid 2 times. Ever since having Covid and going through puberty with hormone changes, he has been having increased symptoms. He is tall for his age (6 feet tall and still growing).

He is on ADHD medication which can cause some of his symptoms (including red/purple skin color changes tied to Reynaud’s and blood pressure changes). His cardiologist also suggested getting more exercise which he needs to do (he is slim/158 pounds) but doesn’t play sports but plays video games and on his phone too much. Exercise can help his heart and lungs get stronger, help him sleep, reduce anxiety, etc.

His cardiologist suggested he get up more slowly from seated positions, drink at least 50% of his body weight with electrolytes added (like LMNT brand), reduce video games/screen time, get good sleep, etc. His neurologist suggested he take magnesium and omega 3 supplements for his migraines and take Tylenol or Motrin at the first sign of his aura in his eyes before migraine pain hits. This has all helped him.

He also takes a multivitamin. Have you had your bloodwork done to check for vitamin deficiencies or toxicities? Do you take vitamins? You should also have your doctor check your iron and thyroid with full blood panels. Are you vegetarian or vegan? If so, you may have some nutritional deficiency causing some of your symptoms like burning and feeling like you cannot breathe. This could be vitamin b12 deficiency or iron deficiency. Do you get heavy periods and blood loss?

Do you have support from your parents to help you advocate for yourself at doctors’ appointments?
