Hello, Thanks for trusting Healthcaremagic! I have gone through your query and I can understand your concerns! Brown recluse spider is a non poisonous insect and it seldom cause life threatening condition. It can cause severe allergic reaction and fever. You don t need to worry regarding this because it can be treated effectively and complications are less. I suggest you to do the following as a first line management:- (1)- You can take avil(chlorpheneramine) or wysonlone for controlling the allergic reactions. (2)- You can take analgesics like ibuprofen or acetaminophen for pain and fever. Apply ice packs over the affected area for symptomatic relief. (3)- A short course of antibiotics may be needed in your case because of pus collection. (4)- A tetanus shot is required if you hadn t one recently. Drink plenty of water to keep your self rehydrated. You don t need to worry as symptoms will resolve in few days. Hope I have answered your query. Thanks. Dr.Shinas
