1 week after wisdom teeth removal here is still swelling on the bottom left side and today i felt the left 2nd molar wiggling. is this normal?

Probably, but: Probably OK, but ask to see the oral surgeon for exam to make sure.

Normal?: You have had surgery. Healing takes time. If you are concerned enough to send this post, then please call your treating Dentist or Oral Surgeon for a post-surgical examination to assure that your healing is proceeding at the expected rate. Do it. It will put your mind at ease.
