Hi, I am 38 old male, pure vegetarian. I was feeling muscle pain (hands) and also I m suffering of cervical pain from the past 1 year. And doctor advised me metilda forte for 3 months. After the course I felt better for few months but from the last few months I can feel some pain in neck. Do I need to take the metilda forte again because Dr. told me that vegetarian normally has low levels of vitamin b12. Or do I need to go to path labs to get b12 levels tested.
