Interesting question Alex...!

I recall a phase (post tx) where I would crawl into a bathtub, and it
was as tho when I sunk into a tub full of hot water, all my veins
showed thru my skin like crazy! I would look like a giant naked jigsaw
puzzle...! It was really rather bizarre....it was SO freaky that I
actually took my digital camera into the bath with me and tried to
take photos of it, but they didn't come out so well. On the other hand
I didn't' electrocute myself or anything trying to take pictures in
the bathtub ;) so alls well that ends well...

I know that I did some research and as I recall, came up with
something referred to as "marbeling" of the skin, and I can't recall
exactly what it was all about except that it reassured me that it w as
not a Big Thing and reassured me once again Not To Panic...

Try looking into that. Bottom line, it passed, like a lot of things
that had to do with Tx and post Tx..... :)

Good luck

I had this really weird thing happen to my skin after I finished tx...
