Suggest Remedies For An Insect Bite
May not be Brown Recluse, but still needs medical attention:
Detailed Answer:
Hello and welcome,
I'm sorry you were bit! Usually with a brown recluse spider bite, by 6 hours the wound starts to be severely painful and itchy.
However, if the swelling is becoming severe, I would recommend going into the ER for observation and treatment. They will likely give Benadryl (diphenhydramine) and may give you a shot of corticosteroids to decrease the inflammation, and possibly a dose pack of this for the next few days.
I'm not sure from your description that it was a brown recluse, but it sounds like you are reacting to whatever bit you.
I am including a link for treatment of Brown Recluse spider bites, for ER physicians, that you may find helpful. http://emedicine.medscape.com/article/772295-clinical
