So I am on day 10 or so of my second sensor and running into the dreaded ???. Yesterday I had x-rays done of my hand. After the appointment I checked my receiver to check my BG and I had the ??? on the screen. I know it had worked right before my appointment because i had checked it at home.
So I waited. I had the ??? once before, and i waited an hour and it finally started registering again. (This happened after a shower.) After 4 hours of ???, I stopped and restarted the sensor. Waited the 2 hours, still had ???. Took another hour and as i was going to bed, it finally kiched in and I eneterd my 2 bg values and went to bed. WOke up this morning with the dreaded ??? and looking over the history of the night, had only sporadic readings.
Is it time to change the sensor or should I wait to see if it will start back up?
