Help me, hives attack!

Since yesterday night, I was having itchiness at the back of both of my thighs. I thought it was due to my trousers, so I changed to another trousers, and continue to sleep. However, at the middle of the night, I woke up because of intense itchiness of the thighs. Scratch scratch there, scratch scratch here, and finally got up to apply Mopiko. However, it still itched. Ignoring it, I tried to sleep, and succeeded.

The next day, the itchiness lessened. I went to hospital as usual. However when I went back and took my bath in the evening, the sense of intense itchiness came back! Damn it...scratch scratch here, scratch scratch there. A phone call to my mum made me realised that maybe it was due to allergy. My mum also had that kind of itchiness before. I took a look at the area of itchiness. OH MY GOD, so ugly. Hives! My skin became like this:

A small area at my medial thigh. My arms looked worse.

I went to a nearby clinic as soon as possible. I could not stand the itchiness anymore. I scared it would become worse and became like this:

My arm is in the process to become like this..T.T

I was given antihistamines by the physician. Hope the attack resolved...I still feel itchiness now after taking the medication and applying cream on it. Sigh...
