i have diabetes type 2. ive been on metformin for it about a year now. i see these commercial for a lyrica for diabetic nerve pain and one of the symptoms is tingling and burning of the feet especially the toes. the toes on both of my feet are beginning to hurt worse and worse. sometimes i forget to not sit on them when i plop on my sofa but the pain reminds me straight away that i have pain in them. when i have to pull my foot from underneath my leg it hurts so bad,feels like when you stub your entire foot on a concrete block. should i be worried?
