My battery hurts, also. The left one burns, but the right one. The one that's been in there for 9 months has been very tender and sore. Really strange. I see my rep Tuesday or some tweaking at six weeks for the new one. I'm going to ask her. This bipolar Texas weather is driving me crazy. It's got my pain levels high even with the stims. Anyway, I miserably failed a vision test yesterday. I have no peripheral vision in either eye. There has been some type of optic nerve damage and neuropathy. No glaucoma or retinal detachment. I see the neurologist the 29th. I'm trying to be positive. But the battery thing, I may take some adil and see if it helps.
