As Dahlek and Melody mentioned - those can be normal side affects of the IVIG - but good you'll see your doc tomorrow.... my normal temp runs between 96 and 97 - and while on IVIG around normal (and high during the infusion itself).... also, found achiness and tiredness very common in the beginning - but after my body got used to the infusions would only last a day or so.....

Hope you feel better - and that all goes well at your appt
