Hey.So last night i was studying when i saw something red on my hand and i touched it and it felt like there was something in my arm.It didn’t hurt.Now i woke up and there is no red but this swelling is still there.My mother said that she thinks that is something dermatological but i am scared it might be cancer.What do you think?Ofc i will go to the doctor but i am just super scared. This is a pic a found on the internet and this is how my arm looked last night.The girl who posted the picture says that it is mosquito bite.

The second photo is my arm in the morning when the redness was gone.
