I have recently had a c-section and gallbladder surgery that have left me with a strange sensation of heaviness on the sternum and the need to breath "manually" . I have been previously diagnosed with Hypokalemia, but had the worst bout last night. I couldn't make my lungs expand enough to take in air for a short period of time, and breathing with the diaphram didn't help...in the mix of the episode, I lost movement of my right arm, and didn't regain use for over three hours...felt it beginning to move to my right leg, but took a potassium supplement to try to help things out...and then finally fell asleep...What could be causing all of this, including the potassium deficiency?
