I have been experiencing since Oct. 2nd or 3rd a feeling of weakness or wobbliness in my legs and arms.Today I was shopping in Walmart (somewhat rushing during lunch hour) after having felt fine this morning (other than some extreme sleepiness on the way to work). I now feel very week, shaky and sleep. I tested my Oxygen level with my phone (not sure of accuracy) and I was at 95%. My bp was between 98 and 102 after having sat for 10 min. (I have been a nurses aid) I was in a high stress and emotional situation with my step daughter on the 1st and 2nd. I have experienced this since then and have also had trouble sleeping and eating. I have no history of heart trouble, diabetes runs on my mother s side, but I have not had any issues as of yet. I am overweight at 256 lbs. and 5 8 . I had my gall bladder removed in Dec 2014 and have noticed that greasy fried foods are bothersome to my system recently more so. I often have acid re-flux due to taking too much ibuprofen during a back injury. I have had about 35 oz of water this morning and 2 cups of coffee. (my norm). I have had my vein removed in my left leg and I often get swelling in my ankles.They are swollen now.
