Hi there ~
I understand your concerns. It is not uncommon to have residual inflammation due to some amount of infection that is also residual in your system after the usage of the medications. It might be worth it consult the same doctor who prescribed you the medications to make sure that you are not having a recurrent infection in which case you might need to use the medications again. I also believe that using over the counter NSAIDs like motrin
or aleev will help mitigate the redness
and antihistaminics like benadry will control the irritation so that you get symptomatic relief. However consulting a doctor will be essential to get the area looked into and to be prescribed the appropriate medications for cure.
I hope this helps. Take care and have a lovely day!
