Steroids or not?

Dear Prayers Warriors
When we saw Dr Ho, the neurosurgeon before he went on leave, he advised us to tamper down the steroids. Pete had been on 2mgtwice a day but Dr Ho instructed us to bring it down ad fast as possible. So Pete been on 0.5mg twice a day for 2 days already. This morning, I gave Pete his 0.5mg but in the afternoon he was experiencing great pain in his tail bone, I had no choice but give him 1mg instead of the 0.5mg which Dr Ho suggested. His pain was so bad he also asked for pain killers and he had started to vomit again this afternoon. He also had fever of 38 degrees this afternoon.
Please pray that I am doing the right thing and that his vomitting and pain will stop. Because of the vomitting, he had not eaten at all except for a few teaspoons of porridge.
Please support us with your prayers tonight. God bless.
