This is Dr. Bonilla, experienced in Internal Medicine, Pulmonary and Critical Care.

I understand your concerns. Penicillin G intramuscular usually last between 2-4 weeks. If the condition is not improving after 2-3 days of treatment you should see your PCP to review your treatment. Let me know if you have any other questions.
