How many hours have elapsed since he was bitten?
How severe is the swelling?
Around 36 hours ago ,
Swelling is obvious around the knee and calf
Is it worsening or has got better than before?
The swelling apears to be moving up his leg and worse than before
Is that area warm to touch as compared to surroundings? Any fever, respiratory problem etc?
slightly warmer than his other leg. No other symptoms.
Thanks a lot for your input.
I am sorry to hear about his problem.
As per symptoms this sounds like a secondary bacterial infection and yes you need to take him to A & E as he may need antibiotics along with a steroid shot.
But you should not stress yourself because serious problem like a reaction is not likely.
