From almost an year, I have pain in legs in one or the other form specially when I stand for long hours or when I start any physical activity. I have had plantar fascitis , inflammation behind right knee , calf tightness & feet numbness sometimes. Though after warm up daily I can dance quite comfortably, pain resumes once I get back to rest specially at night or in office in daily n hip , thigh & lower half of legs. I have been on B12 shots 4m last 2 yrs. I want to have a diagnosis for this.
