Thanks for answering... I thought maybe it would be a clue to what is wrong with me - but evidently they were isolated. They Chiropractor tugged on/adjusted my toe and the blood-shot-eye just went away.
I've been driinking more water. and my feet are a lot less swollen, As far as other issues (such as heart or kidneys) - not that I know of and the doc didn't find anything a couple of months ago.
