I need help! Are those side effects?

Hello,

I did OP a while back,like a year ago for almost 4 months with sunflower oil. It did help alot with my teeth and stomach ache. I stop doing it and just started again like a month or so and this time with Coconut oil. Three weeks ago,i started coughing up a lot mucus which i believe from my nose ( It happened last time when i OPed too),so i strongly that it was the sign that the OP was working. However, i also experience shortness of breath,and i always feel like something is stuck right at my throat ( i think its the mucus). Just wonder if anyone has the same experience as i have? I just switched back to sunflower oil 2 days ago. Hopefully those "side effects" will go away.
