This depends on the type of spider, your tolerance to venom,and your immune system.
Nearly all spiders are venomous,and enzymes in the venom are such as to break down organic tissues.
With all but a few species of spider, you immune system heals the damage faster than it can occur,
and these bites are insignificant.
Bites from medically significant spiders, can become more severe, causing dermal arachnidism.
This is an elevated skin damage and usually takes much longer to heal. In rare cases, this can lead to dermal necrosis. a self degenerating condition where skin tissues are destroyed, and often requires medical attention to stop the progress of damage. In extreme cases, tissue damage can continue to include fatty cells and cellular damage to muscles. without treatment this can become gangrenous, causing major damage. Usually this takes some time to do any serious damage, and if treated early, rarely become severe.

That depends on the spider. for necrotic venom spiders it usually takes a few weeks.
