Hi there ~
I understand your concerns. If you have been using cocaine and noticed swollen lips, spots on the chest, hands and feet and have been diagnosed with infection; you are probably immunocompromised due to either long term illness of substance dependence
or another infectious disease. Please consult a psychiatrist
who can take a complete history and give you medications and the appropriate referrals to get you on the path to recovery. You probably also need to consult an ENT consult due to having pharyngitis
and need to be thoroughly examined for the same.
I hope this helps. Take care and have a lovely day!
