Jayden is Allergy to Something!! Or is not??

Last Sat while having dinner outside, I noticed that Jayden have red spots on his legs, so I thought it might be cause by the heat from the hot weather. Since recently weather have been really really very hot. So I ignored it, thinking it will go away itself.

Sunday, woke up and saw that the red spots began to spread. Even to his face... Thinking something must be not right... At noon, it got worsen. It even got itchy if he sweat and he will scratch and scratch... Went to mum's there and mum say he is bitten by bugs. But I don't think so cause I know what it looks like if being bitten.
Then at night the red spots and patches are all over him. Mum keep bathing him in cold water with dettol. Wanted to bring him see doctor but Sunday not many clinic got open so waited till monday...

Monday bring him go see doctor at 9am. Got alot of people. 16 people before him. So waited. 1020am, still got 8 people before his turn. So fed up cause weather very hot and he keep running and cause himself to sweat so change another clinic which have no people. But I wonder the doctor really can or not. He say he don't know what really cause him to be allergy untill so serious. Its either he got bitten by something or he eaten something. Given me medicine to stop the itch. One to eat, one to put on. Say if 2 days later still like that, must see doctor again...

Today, still see alots of spots and patches...
If tomorrow still like that I will bring him see another doctor.
Althought he looks like very sick, luckily still very active and can eat. If not, it must be very serious. Doesn't look sick except for those red spots and patches.
