What to do if i had a vaccine shot and it still hurts like a biatch?

It depends: If you tensed your muscle with the injection, you may have tenderness for several days. Tylenol (acetaminophen) or Ibuprofen may help. If there is redness or swelling more than a couple of days, there may be an infection at the site. See your doctor.

Pain : Ice , painkillers like paracetamol and brufen can be tried . If there is redness , swelling at injection site or fever then please see your doctor.

Ouch: try ice paracetamol antiinflammatory etc. if red around site or feverish need to seek urgent medical assessment
