I've been sick since Thursday(38degrees celcium but it very fast went to 36.8 and still stays this way; a killing sore throat; nose size and colour like a tomato and leaking like a tap) and my hair is so oily that you have no idea, but I can't get ta shower because It could cause complications...
Hang in there man! Get some rest. Sometimes if my hair gets nasty I just tie it up. That way it's not so noticeable.
My mum has/had some dry shampoo that you spray in your hair and it cleans it, not sure how it works but it may be worth getting some in case this happens again.
Last fall I could not wash my mane or beard for three weeks, not even just in water, and I survived. Doctor's orders to avoid infection to a neck wound. My hair stabilized after about a week, and yeah it was a tad bit funky, but it was fine otherwise. It suffered no damage due to the ordeal.

If you can't get your head wet, try combing a little bit of corn starch through your hair. It will remove the excess oil. I use it on my hair to remove excess oil.
