you are doing the right thing for the immediate treatment
I know that these spiders are a problem in the Tennessee area, did you and neighbour call an exterminator or something, I think you should it will be the first treatment get raid of the source
most bites are asymptomatic, envenomation can result in a constellation of systemic symptoms referred to as loxoscelism. Patients can also develop necrotic skin ulcers (necrotic arachnidism). These ulcers are often difficult to heal and can require skin grafting or amputation of the bitten appendage.
Most brown recluse spider bites are asymptomatic. All bites should be thoroughly cleansed and tet**** status updated as needed. Patients who develop systemic symptoms require hospitalization. Surgical excision of skin lesions is indicated only for lesions that have stabilized and are no longer enlarging. Steroids are indicated in bites that are associated with severe skin lesions, loxoscelism, and in small children. Dapsone should be used only in adult patients who experience necrotic arachnidism and who have been screened for glucose-6-phosphate dehydrogenase deficiency. Topical nitroglycerin can be of value in decreasing the enlargement of necrotic skin ulcers
Treatment of these bites is controversial and is generally directed at managing the cosmetic injury to the integument. A secondary focus of treatment is the management of the less frequent but potentially more serious systemic effects of the neurotoxic venom, often referred to as loxoscelism. Gangrenous spot, or necrotic spot of Chile (dermonecrosis), as a consequence of the bite of the venomous South American brown spider (Loxosceles laeta) was initially described by Macchiavello in 1937
The collection of adequate volumes of brown recluse venom for biochemical ****ysis has been difficult and challenging. Researchers have attempted to collect and fractionate venom for study by using electrical stimulation and microdissection of the venom glands. These studies have indicated that the hemolytic component of the venom is heat labile, calcium dependent, and optimally active at a pH of 7.1. Collectively, research to date has shown that purified brown recluse venom contains a minimum of eight or nine different enzymes and proteins, including alkaline phosphatase, esterase, lipase, protease, hyaluronidase, hemolysins, levarterenol bitartrate, and sphingomyelinase D. Sphingomyelinase D is the most important and most active enzyme in brown recluse spider venom.
Treatment Regimens for Brown Recluse Spider Bites but yours is very efficient since it healed very fast with very low damages.
Early and late surgical excision of wound
Wound curettage
Steroids
Dapsone [Dapsone treatment for BR spider bites has been found to alleviate the need for surgical intervention in some cases. Dapsone is an inhibitor of neutrophil function, a major mechanism of skin necroses brought on by envenomation. G6pd deficiency and methemoglobinuria are contraindications to Dapsone therapy due to potential massive hemolysis in individuals with these disorders.I suggest you to get some in case of other bites more serious ask your doc for it]
Hyperbaric oxygen
For mild lesions, broad-spectrum antibiotics and antihistamines are used.
It is important for the patient to capture and bring in the spider, if possible, to help determine the necessary treatment.
Poisoning by spiders of the Latrodectus genus may require intravenous calcium gluconate alternating with methocarbamol to relieve muscle cramps. These drugs are usually a part of the management by the emergentologist.
Victims of poisoning by members of the genus Loxosceles may require hospitalization if sequelae develop. Hydroxyzine 100 mg may be given by the emergentologist to alter the necrotic lesion.
If hemolysis develops renal dialysis should be started within the initial 48-72 hours. Surgery may be required for large necrotic bites that extend into the fat.
Antivenin is available for bites by spiders of the Loxosceles and Latrodectus genera and is very effective if given soon after the bite.
Because of the excellent blood supply to the eyelids, the lid margin may be spared of gangrenous processes, and a propensity exists for self-repair.
Complete blood count and observation of potential problem cases should be recognized early.

Basic treatment plan for brown recluse (Laxosceles reclusa) also known as the fiddleback spider.
High voltage, low amperage shock, using a modified stun gun of 26 kilovolts at 350 milliamps. For spider bites of the recluse variety it is necessary to go from one side of the limb to the other by means of a #10 stranded wire jumper cable. This is necessary because of the deep penetration of the venom. The central area as well as the surrounding area of erythema is shocked up to 6 or 8 applications. This is like getting a jolt from an electric fence and is tolerated quite well by most all patients.
Patients are then observed for up to 2 hours. Since a sudden release of toxins and foreign proteins may result in some renal impairment, it is advisable to obtain a urinalysis several hours after treatment.
Patients need to be updated on their tet**** immunization.
Patients are routinely placed on antibiotic therapy with cephalexin, 500 milligrams twice daily for 7 days.
The addition of Dapsone 50 mg. twice daily is a controversial issue, but I find it most advantageous for 7 days.
High voltage, low amperage direct current shock has been used with great success in this and other types of envenomation. Treatment consists of using a modified stun gun that will produce 25 kilovolts at less than 350 milliamps. Because of the deep penetration of the venom of the BR spider it is necessary to shock "through the tissue" rather than surface shock only. This is accomplished by means of a jumper cable attached to one pole of the stun gun that will reach to the opposite side of the extremity. The central area as well as the surrounding area of erythema is shocked 6 to 8 times. This is like getting a shock from an electric fence and is tolerated quite well by most all patients. Patients should be observed for up to two hours since a sudden release of toxins and foreign proteins may result in some renal impairment. It is advisable to obtain a urinalysis several hours after treatment to check for hemoglobin and myoglobin. The mechanism of action is still debatable. Some feel that it inactivates the proteolytic enzymes and some feel that it gives the cell wall a higher energy state that inhibits the attack by the enzymes. It probably is a combination of the two.
Routine tet**** booster and antibiotic therapy is indicated. If Dapsone is used, 25 mg. two to four times a day seems to be an appropriate dose with minimal side effects.

hope this get you more info and management but keep your way which I think is very good beside of Dapsone
thanks
