Hi my name is emma and im 18 years old (well turning 19 in a month) Anyways, i came back from school today and slept like 4 hrs but when i woke up my pinky was swollen and theres this beed like sensation at the tip of my pinky, its also kinda itching, what could have caused this? One more thing, 2 days ago 2 red bumps appeared on my left arm and they seem like mosquito bites but they were sooo red and itchy and swollen, could this be an allergic reaction or something?
