I have been suffering from nerve pain, dizziness, light headed, nausea, faint, and swell up from tie to time in hands, arm, knee, and feet, feels like I,m walking on pins and needles often, my hands always hurt, it feels like a tingling numbness. I ve been feeling like this for years along with rashes with sun exposure. I have a primary care doctor I have been seeing for years and have been diagnosed with several things and wanted to know if these symptoms could be one thing overall instead of several things. I m so tired of taking 10-12 pills a day and the side effects make me feel worse.
