for several years now i have had a number of medical issues. I have had palpitations, pins & needles, nausea, stomach aches, dry mouth, twitching/sore/inflamed tongue, hallucinations, hypotension, irregular heart beat, sleep apnea, muscle twitches, lower back pain, i had rapid weight gain which resulted in stretch marks on my stomach, arms and inner thigh. Some of these symptoms all at once in several different episodes which last a few weeks, then most of the symptoms subside. I was told a couple of years ago that i was getting the side effects of some stomach medication i was on (lansoprazole) and have since come off them. I am now having another episode of the symptoms above. I was searching the internet and found hypokalemia which seem to have similar symptoms. Does anyone know any more about this condition and/or whether they think i might have it.
