HI, I have a history of blood clots on the lungs, 20 years ago, anyway, the last few days ive been feeling not like myself, I m very energetic, I started yawning and cant seem to stop, I take very deep breaths, My back of my throat seems like its getting sore from consistently yawning, also very very tired. I am on blood thinner which my last two INRs were very high. 3.44 & 3.36.. Its making my chest kinda tight, but not to bad, What do you think?
