Hello dear user! I have gone through your query and understood your concerns! Thank you for sharing them on healthcaremagic. Well you have most likely a strep infection since your throat hurts very bad and it s very red. Pain feeling in your body is due to a possible pass of bacteria in your blood. You might have high temperature too. Anyway this condition must not be left to pass away by itself. It would be better for you to use a cure with antibiotics. I would recommend you augmentin for your strep infection, an antiseptic spray for your throat and vitamins. Consult your pharmacist for the way of use. Have a lot of liquids, and a light diet and you will pass soon this situation. I hope this answer was helpful to you! Please kindly rate it as helpful and write a short review about your experience with me! I would appreciate that a lot. Thank you and best regards! DR ERIOL.
