Had 3 bug bites 2 months ago. Formed a hard welt on one bite. All 3 continue to really itch. One scabbed. How to get rid of?

But bites: The firm mass at one bite site may be a small blood clot (hematoma) from bleeding under the skin which occurred at the time of the bite. As long as these bite sites are not hot and reddened no secondary infection is likely and you can apply a cortisone type ointment to relieve itching. The hematoma may very slowly resolve. Read more

Bed bugs -itchy bite: I think 'yes' these are from bed bugs. These are insects and so their bites can certainly cause an allergic type reaction, just like a mosquito bite. New York City has a real problem with bed bugs as you might be aware. Hopefully you can avoid contact in the future because you will react the same way (or worse!) as allergy gets worse w/ time. Good to check with a MD for questions, esp. If worsens. Read more

Infected Insect Bite: Insect bites can cause redness, swelling and itching. In some people the amount of swelling can lead to bruising. However, if the area is more warm than the normal appearing skin, if it is very tender, and is spreading in size, see MD to rule out possible bacterial infection of the skin known as cellulitis which needs antibiotics promptly.
