I've got lower back pain due to menstruation and i'm wondering in CBD can help with that.

"looking for possible MG dosage im 130 pounds 5'3 tall."

First, everyone reacts to CBD and cannabis differently. However, we have seen improvement at 2-5 mg but up to 20 mg per day. It has more to do with your metabolism that your height and weight. It is def. worth a try.
