I know that fingers of hands (and feet) represent 10 commandments. Right arm first five and left arm second five. So if you have a pain in the right arm it is likely you are violating all first five commandments. If it is just one finger then it is just one commandment.
Tabernacle were also designed to mimic human body of sorts. I.e Ark was the head/brain. Altar for Slaughters was a stomach etc. Please see Leviticus 15:31 and Numbers 19:13
Not to mention that all measurements in the Torah have something to do with human body. I.e cubit is a forearm, omer - handfuls, e.t.c.
Otherwise Torah says that God is your healer and if you live by the Written Torah alone, you will never be ill. See Exodus 15:26 or Deuteronomy 32:39.
I also think that Deuteronomy 2:20, for example, refers to healers (רפאים rpaim). It was a nation that knew how to heal. They possessed ancient medical skills.
Torah allows medicine as a science though because it is mentioned in Exodus 21:19 as a method of atonement for the sin. This verse also implies that it is ok to charge for medical services because in this case perpetrator was wrong so he must be held accountable through medical costs.
