I take 20 mg Furosimide daily & have for a long time for congestive heart failure - I was taking 40mg but my dr reduced it to 20 - I have severe muscle aches & pains in my upper arms - very severe - I have no chest pain or shortness fo breath - all the literature suggests that Furosimide can cause these aches & pains - is that what i am experiencing - I also take magnesium & potasium daily as presecribed - thank you - Ian Singer
