Welcome to JA and thanks for asking
If you have developed infection in that area you need a course of antibiotic.
For relief of pain and inflammation you can take anti-inflammatory like Ibuproen and for hives anti histamine certrizine.
So my advise would be to see your doctor for an antibiotic course. At time in mild cases even local application of antibiotic cream also does the job
Feel free to ask if you have any more question
