I have had a cold with chest congestion, spitting up thick brown mucuous. It seems to be getting better and I never ran fever however I feel like fluttering in my chest as if the mucous is moving around.. I don't think it is heart palpatations as my pulse seems ok...I do take Losartan and Metaphorim as well as Lasix once a day...I was off of the lasix this past week as I was taking cold medicine and I do not do well when mixing all the meds...Just kinda of concerned as I don't have medical insurance and was wondering if you can have that feeling of fluttering from chest congestion..i have had no pain at all
