Hello i have been getting this feeling that sort of Buzz/ Fizz on the left side below my bra, I ask the Dr a long time ago he listened and said he couldn't hear anything , Im under a Hospital in London for my Asthma ( only just been first time) and they gave me a heart test, nothing then its still going and to me getting more often I went into a Hospital they put me on a heart thing I sat still and it didn't do it !!!!! They told me to see my Dr again ( I haven't yet ) this was over 4 weeks ago and its still doing it anyone know what it might be ??? Im getting my lungs Scanned soon will it show up anything to do with the heart ?? Thanks for any help that may be offered
