I never saw the porphyric hemophelia come up on the screen. I got it from the gutted mine in azuras shrine...and i was so focused on defeating the orcs...i didn't pay attention. The orcs were like hell for me, it was either dying or getting the disease that made me hav to reload the game and put me back at the beginnning of the cave. I must have missed it coming up once.
p.s. you can prolly heal helljoint at one of the temples in the cities. I can't remember which ones cures diseases. I think either Anvil or Cheydinhal.
Bethesda makes the best games ever. The Elder Scrolls games rock harder then any other game ever. I like Heavy Metal and Death Metal. My favorite band is DevilDriver.
