question: I was diagnosed with pnuemonia of a lower lobe on Saturday. After starting a five day antibiotic and inhaler, plus some mucinex and tylenol,  Im feeling much better (able to get out of bed and interact with the family). Last night I had to sleep sitting up because laying down for too long makes my lungs sound like they have pop rocks in them and I have nightmares of being choked. Now Im having severe coughing bouts that are returning blood tinged sputum and small pcs of what appears to be a tissue like substance (not mucus).  Should I be concerned or is this just part of the healing process?  My doctor doesnt have an on call service and Im a little scared to be seeing blood, but I dont want to drag my kids out at night to go with me to the local ER for nothing.
