For many years I worked at a job where I was required to be on my feet for nine hours straight with no breaks.  I experienced the same thing with my feet.  A year after I quit that job the problem corrected itself.  I believe it was over stressing my feet, causing the blood to rush and stay in that area triying to heal my barking dogs!  My hands did the same thing but that had to do with spending long periods of time in the walk in cooler stocking beer and sodas.  Change the setting on whatever camera is causing your nose to look red on photos!
