last night i went to bed feeling fine, woke up 3 hours later with a cold sweat, mainly my head was wet, my face felt hot and flushed and i felt like i was not getting enough air, i was taking deep breathes but didnt feel i was getting a full breathe or air, i checked my blood pressure and it was 161/84, but the day before i had a pain in the back of my shoulderblade on the left side, i took a hot bath and was able to breathe a little better, i coughed up some fleem and some of it was dark, i felt a little wheezing before i started coughing, i worked thru the day but still do not feel i'm getting enough air, and i could not lay my head back on my pillow afterwards last night without the feeling coming back like i couldnt get a deep breath, could it be fluid in my lungs, have not had any chest pains, just feels like it catches when i take a deep breath
