Hello Doctor. My doctor prescribed Lasix for me for the first time today to treat edema in my lower legs, ankles and feet. I have chronic asthma also which, especially at the onset of Spring, I begin to react to whatever irritants cause me to react, then comes the coughing, sneezing, lowly feeling, spasms of coughing attacks from my lungs which are expelled with hard coughing but still very clear. The spasms lead me to believe there is too much mucus in my lungs. Will Lasix help this an thus help the swelling in my legs/feet? I never used to swell from my blood pressure med (Ex-Forge) but this year I began to. I think it s all related.
