Hello, Thanks for the concern. You have history of 2 episodes of shoulder pain and throat pain and had taken medicine. But sill you have the same complaint but severe. So for that you have to avoid cold drinks and cold foods, Luke warm water gargle having turmeric powder and salt ( avoid salt in gargles if high blood pressure) twice daily. You should take pain killer with paracetamol for pain in throat and shoulder. You should do blood test having WBC count, C-Reactive protein which indicates infection, also throat culture which will show the type of bacteria that helps in choosing appropriate antibiotic. At present you can take antibiotics like combination of Amoxicillin (500) and Clavulanate Potassium (125) twice a day for atleast 7 days. So consult your treating physician, get investigated and start treatment accordingly. Hope you might get help. Take care.
