My husband has been suffering from pain in his lower back, calf muscles and feet... in consulting the doctor we were told that this is a
vitamin B12 & D3 deficiency... hence my husband took injections for the same...after the treatment too there has been no significant change in his condition... he always feels tired and on several occations the pain and stress in muscles is so intense that despite taking a full night sleep he is unable to get up from the bed... kindly guide as to what could be the possible reasons for this pain...
