My brown recluse bite is still painful. Is that normal?

Uhhh.....I wouldnt so far as saying all fear and anxiety-inducing stuff the person above me said. But I agree that you should see your doctor again , Amethyst. Brown recluse bite should resolve itself sometimes even without any medical help. The fact that antibiotics did not work for you represent a possible larger problem. But there wont be any use speculating until you ask for your doctor consult.

The Recluse spider venom is a collection of enzymes. One of the enzymes, when released into the victim's skin, causes destruction of local cell membranes, it then disrupts the integrity of tissues leading to local breakdown of skin, fat, and blood vessels. This process leads to tissue death (necrosis) in areas immediately surrounding the bite site.

The venom also induces in its victim an immune response. The victim's immune system releases inflammatory agents-histamines, cytokines, and interleukins-that recruit signal specific disease-fighting white blood cells to the area of injury. In severe cases, however, these same inflammatory agents can themselves cause injury. These secondary effects of the venom, although extremely rare, can produce these more significant side effects of the spider bite:
- Destruction of red blood cells
- Low platelet count
- Blood clots in the capillaries and loss of ability to form clots where needed
- kidney damage
- Coma
and if left completely untreated; death.

I would highly recommend you see a specialist if the wound hasn't healed even with the assistance of antibiotics.

I agree with Sleeping Giant. Typically these bites will heal just fine. The pain is not often severe, but will likely be aggravating and persistent. The pain will diminish as the wound heals,and may take some time.
Many of your symptoms are likely side effects of the antibiotics.
Statistically, 95%of these bites heal nicely on their own.

That's a good observation
