Common symptoms of a brown recluse spider bite include shivering, vomiting, nausea, fever, itching, shock and restlessness. The bite may come out as an injury of about 1 to 2 3/4 inches which takes several months of healing and will leave you with unsightly scars. The bite is usually deep and will cause pain eventually.
Despite the large wounds often associated with brown recluse, they are much less likely to cause significant injury than black widows. Skin infections may cause boils, which are often misdiagnosed as brown recluse spider bites (see spider bite pictures).
