Red, Hard Bumps On Legs That Look Like Bug Bites. What Could They Be?
A few weeks ago, I noticed a few red bumps on my leg and assumed they were mosquito bites. A few days later, there were about 15 bumps. They have turned hard, itch and are sore to the touch. Lanocane helps stop the itching but the bumps are not going away. Should I see a doctor?
There are many different causes of red bumps so it is impossible to say with any certainty what might be causing this. Some possibilities include:
Bed bugs - Bed bugs can cause red bumps on the skin that are itchy. They usually disappear within a few days but if you do have bed bugs, you can continually have bites.
Flea bites - When bitten by fleas, you can experience small red bumps that resemble a rash. They may or may not bleed and often itchy. You might develop hives. Flea bites tend to be in groups of three or four and are most commonly found on ankles, armpits, around your waist and in the bends of your knees and elbows.
Ant bites - Some types of ants bite. It can be painful and result in a red bump, which ends in a blister. The blister can remain for up to about a week. Ant bites can be itchy.
Mite bites - Mites, including dust mites, can bite or cause an allergic reaction which looks like small bug bites and can be itchy. The bite of chiggers, which is one type of mite, will turn hard around the bite.
Scabies - Scabies are from mites that burrow under your skin. The red bumps can look like acne and be very itchy.
You did mention that the bumps became hard after a few days. This is one of the characteristics of Chigger mite bites. A dermatologist should be able to help you determine exactly what is causing your red bumps and provide you with information for treatment and prevention.
