I have had many aches and pains since contracting bacterial meningitis a year ago. Strong headaches, neck & spine pain, muscle pain, to name just a few. The Dr.'s are uncertain as to why I am experiencing sequale so long after the disease. Recently my lower back woke me up in the middle of the night in excruiating pain. I had not done anything to hurt it. X rays revealed nothing. I then started experiencing muscle cramps in my hands and feet and a fast, irregular heartbeat. I had a regular check up 4 days ago, and labs were taken as they are every 3 months or so. The nurse called yesterday and wants me to come back in for a retest. My potassium level was 5.9. She said it should be 2.?. I'm thinking it is probably just a blood draw problem, but with the new uncomfortable symptoms I'm wondering if anyone else has experienced this and if so, is this anything to be concerned about? I can't go back for blood test til Tues. & it takes another 3 days for results to come in.
