Hey all I'm back. I'm still having issues breathing. Feels like chest tightness and hard to take deep breath without yawn. I'm still on my regimen. I'm taking two spatone liquid iron a day at separate times to make sure it's not iron. Folic acid 5mg,potassium 5mg through food, omega 3,magnesium glynicate, biotin,D3&K2,b12 inject every rqo days for the last 5 months. It comes and goes but im getting tired of it and about to ask for referral to a lung doctor and heart doctor. I dont think its normal to feel like you need to take deep breathes or yawn to get enough air. Also getting light headed when standing.
