I have been prescribed Lidoderm Patch 5% to help me stay mobile cuz I weigh 300 lbs n my knees need to be replaced but I'm too high risk for blood clots. My back also kills me. I have extreme high pain when I get up to walk. I have 2 use a walker n sometimes a wheelchair. Now my insurance does not want to pay 4 the patches anymore cuz I've never had shingles. I'm trying 2 find reasons to try n talk them into letting me have them or I'm right back stuck sittin all day n no life!!
