update:
Hubby said the temperature has gone and no more red eyes. The tongue is still like a sliced strawberry, haven't asked about the lymph node.
The very high dosage IVIG worked (standard treatment for Kawasaki) and now taking aspirin. As IVIG is a blood product, there is certain risk to take and I think that's why the doctor was being conservative. So getting better in general.
I am about to go to the hospital and will report again tonight. Thx all for your concerns.
(thanks in advance for volunteer translation)
