Re: HELP! Are antibiotics still needed if there's still pus?

If what you have was caused by a spider bite, antibiotics are often ineffective, as they work only against bacterial infections which might be present but may not be effective against spider venom.  On the other hand, you may have a bacterial infection that is resistant to antibiotics.  In either case a good quality colloidal silver could be part of the solution.

I suggest you look here and follow the instructions for Brown Recluse and Other Dangerous Spiders.

And afterwords you may wish to also look into a good healing ointment and healing capsules such as the ones MH has (the Ask Barefoot forum).
