The feet that won`t cooperate

Beppu Day#2
So here we are, in Beppu, the city of many onsen. We arrived last afternoon after a long train ride from Koyasan.
I have spent the entire morning at various hospitals having my feet looked at. A wonderful chap from the hostel drove us around and translated for us. I`m still unsure as to what is wrong with my feet. We are going to see a specialist tomorrow, to make sure I don`t have deep vein thrombosis. Just to assure everyone, we are pretty sure it is not DVT, because the swelling is in both my legs and the swelling comes and goes. I think that I just have edema, from a variety of reasons (sitting a lot on trains, dehydration, a reaction to the heat and humidity here, drinking caffeine, etc.). I am drinking lots of water (with electrolytes), resting, and walking. My feet don't hurt, unless they are really swollen and then the skin feels funny. Good thing I have medical insurance that will reimburse me when I get home (thanks so much Mandy!!).
To give my feet something to do we are going up to the mountains for a walk around to see some `hidden` natural onsens.
I will write more about Koyasan later (when I can use a computer key board that functions properly and is not such a pain in the ass to use). It was the best experience of the trip so far.
