I have been light sensitive from living in the desert too long and old age .. I know of no cure for that one. Ringing of the ears, joint pain and lack of excellent balance can all be cured with Tamanu Oil placed on the skin behind the ears or on the area where the joints pain is occurring. I feel like the guy in "My Big Fat Greek Wedding" with this oil. I don't know what it will no help from screaming eyes and running nose while baling hay to cuts and bruises. Get from a reliable place as it should not be over 12 months old.
