[|Human|] A year ago I was in the hospital with CHF.  I have been well since then but lately have started having a shortness of breath again and edema in ankles and feet.  Sometimes when I take a nap I am awakened by pain in my shoulders. Should i be alarmed with this?
[|AI|]  Hi welcome to Chat Doctor... You have not mentioned right sided or left sided heart failure .... In CHF venous return may get impaired and edema can be there .... Back flow due to inability to pump blood forward can lead fluid collection in lung and pulmonary edema can be there leading dyspnea .... For edema, you need diuretic therapy with furosemide like Chat Doctor. . If needed oxygen therapy given ... You need to consult physician for examination and investigate with ....1. Digital chest x-ray 2.EKG etc.... Take care ...
