I've been getting these itchy bumps with a red dot on top over a few days. They appeared in number on several places on my arms and legs. I usually find them when I wake up from a deep sleep. I think sometimes the itch itself wakes me up.
My place is kept clean, no pets, hardwood floor, and no blood stain anywhere on mattress (bedbugs?). They disappear in 2-3 days leaving a red/dark round mark.

This is how they appeared:
1st batch- On the top side of my lower right arm but closer to my elbow-joint. 4 bumps, not in straight line, about 2 inches apart.
2nd batch - On the palm side of my lower right arm, 2 bumps about 2 inches apart.
3rd batch - On the palm side of my lower right arm, around my elbow-joint. 4-5 bumps, not in straight line, about 2 inches apart. At the same time on the top side of my lower left leg, closer to knee. 4 bumps, not in straight line, about 2 inches apart.
Current batch - One on my left pinkie palm side, 2-3 near my left toe, 2-3 near my right pinkie-toe, 2 on my left feet, 1 near my waist.

Please help me identify this insect.

Welcome to e health forum.

Any Dermatological conditions cannot be diagnosed without a proper medical history and physical examination.

The most common sources of insect bites in the home are bed bugs, human fleas, pet fleas, bird fleas, ticks, Spiders, and other bugs. But the exact insect cannot be identified just by the history provided here.

Most Insect bites will result in varying grade of inflammatory reaction which can result in symptoms like pain, redness, mild swelling and itching.

In addition, inflammatory response of the body, which varies from person to person, changes the appearance of the bites.

Keeping the wound clean with antiseptics and use of topical antibiotics (triple antibiotic) can help prevent secondary infection and aid healing. Use of antiinflammatory medications can help with any swelling and pain. Any associated itching can be helped with the use of antihistamines (benadryl).

If you have any doubts, consult your doctor and seek proper advice.
