I have been having general fatique. Sleep all night using a CPAP. Wake feeling well. by 2:00 extreme muscle fatique and I fall sound asleep in a chair. Extremely dry mouth although drinking plenty of water and urine appears to be pale green. Sometimes pain in lower back on the right just below the rib cage. upper arm muscles weak and painful. I have a rhuematic heart but have not experienced any abnormal beats or flutters. No fluid retention in ankles or feet I won t have insurance until 1/1 and money is quite and issue here.
