Thanks for asking the query,
Swelling near the eyelid is due to the spider bite
, make sure that you are immunized for tetanus
if you are not so in the last five years. Infection caused by the spider bite can be treated with the help of antibiotics.As such most of the cases of spider bites heal by themselves.
For toothache you need to visit the Dentsit and get the checkup done, take an x-ray of the tooth,if the tooth is re-infected you have to go for re-RCT.
Take complete course of antibiotics and analgesics.
Maintain a good oral hygiene
Hope this helps out.
