I'm a little late on actually reading this thread. I grew up in SoCal so had to deal with tarantulas and black widows all the time. Here are the listed symptoms for black widow bites.

Initially, almost all bites from the latrodectus species is felt as an immediate pinprick sensation, and local pain. In approximately one hour after the bite, a small, erythematous area develops. This becomes larger with a blanched center. The venom acts through a calcium-mediated mechanism, which is the release of acetylcholine and nor-epinephrine. Subsequently , the vast majority of patients, around 70%, do experience hypertension, nausea, light sensitivity to the eyes, which is called photophobia, difficulty breathing, diarrhea, and muscle spasms and aches. These individuals can present like an acute abdomen, and mimic a ruptured ovarian cyst or appendicitis. In one study in Australia, however, around 70% of the individuals only presented with local symptoms and did not present with systemic symptoms.

Drizz, are you positive you didn't rupture an ovarian cyst?
