Thanks for your question. It is often not clear what the initial injury
is that starts some of the common skin injuries that people associate with spider and other insect bites. In most cases, this is not necessary to be properly treated and to make sure that you recover fully. It is good that your original wound has healed, but I am not sure what you are describing by talking about these other bumps. Sometimes people will have allergic reactions to some of the different antibiotics that they take, and it could be that you are simply having a reaction. Alternatively, there could be many other explanations that could clarify what is happening. It is important to speak with your doctor
about this question to know for sure what the next best step can or should be. For those who don't have insurance, this sort of problem can often be resolved with a phone call, as your doctor should be able to make some suggestions without needing to see you in person depending on how severe your symptoms are. There are some common findings with poisonous bites that can be found online, but please speak with your doctor.
