Could be kidneys if dehydrated, are you getting your electrolytes (I like Electro Mix by Emergen-C). or it could be your adrenals cause might be over working your body (they are located by the kidneys and can hurt bad when body is exhausted).

About RIGH: support held at 7 which is good and our next move up should be higher then the last high especially with Washington opening the door to MJ on July 1st!
