It must have been a mosquito or similar and now I've got a big, itchy swelling on the inner side of my arm, above my elbow, but it's not hard like normal mozzie bites. First it looked like a normal mosquito bite but then it got bigger, swollen and more itchy. I've wiped it with onion slices and wiped it with a warm cloth. Then the itching gets better but the swelling gets no better. I got it bit yesterday. Any idea? Should i consult a doctor?
