疙瘩 (gē da): บวมหรือก้อนบนผิวหนัง

After being bitten by a mosquito, a red lump appeared on my arm, and it was very itchy.

She noticed a small bump on her face and hurried to the hospital to see a dermatologist.

The doctor felt the lump on the back of my neck and said it might be inflamed lymph nodes, so I needed medication.

Xiaoming fell down and a big bump swelled up on his knee, so his mother immediately applied an ice pack.
