Hello dr. I live in northern michigan and I was bitten by some type of insect on my leg. Its itchy swollen and looks like a \"flat hard bump\" about the size of a dime. its sore to the touch and its pulsating. what type of insect could this be from and why is it pulsating?
HI whatever insect it had been, it looks like its bite has caused a local infection. Its one of the signs of local infection and swelling that pulsating feeling. The inflammation is caused by the chemical substance that the insect has injected in your skin by batting. I recommend you to take orally antibiotics like Augmenting 625\u00a0mg twice daily and a topical cream like defense Chat Doctor.  If not improvement contact your dermatologist or infections. All the best for you!
