Hi I am a 77 year old male and have been treated for type 2 diabetes since 2005, i have been taking 2 x 80g Gliclazide tablets a day since i was diagnosed. Recently i felt my blood sugar was not under control and after blood tests my advised blood sugar readings were slightly above the recomended benchmark. He proscribed i take 2 x 500mg Metformin Prolonged - release tablets once a day after evening meals, within days i experienced side effects, during the day i felt fine when i go to bed i would wake in the middle of the night with a burning pain in my right little toe which after a few nights also also happened to my right toe. On getting up and moving about the pain disappears, over progressive nights the pain got worse effecting the lower section of the little toe on each foot. I reduced the Metformin to one tablet and immediatly the pain lessened and disappeared from my right toe and diminished in my left toe to an extent i could sleep through. My thoughts were that the Medformin was causing gout! Anyone else had the same problem?
