Stormarksgothi,
Is there a Norse god(dess) of Health?
Good Morning To You, My Dear Heidi,
Although I must say that I am eminently "unqualified" to answer your question concerning Gods or Goddesses of Health, I feel that there surely must be at least one God or Goddess of Heallth . . .
Since there are many Gods and Goddesses who take care of various "departments" in Life, I would assume that Health would, just naturally, fall into a category of such a Deity . . .
However, please, I defer to the Stormarksgothi for a Final Answer . . .
Have A Most Splendiferous Morning . . . Forthwith . . .
Eir is the Norse goddess of healing, which is probably what you are looking for.
Good Afternoon To You, My Dear Gentle Friends,
Well, A Goddess of Health Is Definitely A Valuable Asset To One's Positive Outlook In Life . . .
Have A Most Splendiferous Afternoon . . . Forthwith . . .
