Hi. It seems like you have a bad case of acute pharyngitis. It may be viral because of the muscle pains but it doesn t rule out a strep infection too due to the high fever and severe throat pain. It can also be a combination of both. It is not necessary that other people you have been in contact with have a strep infection too. The infection depends greatly on individual immunity which differs from person to person. What you need is a good course of antibiotics, anti-inflammatory medications and oral antiseptic rinses. You also need to keep yourself hydrated adequately by drinking 1.5 -2 litres of water everyday (will hurt initially but will ease swallowing slowly) and eat soft bland food. You will need to see your primary physician or an ENT specialist to evaluate your throat and carry out blood work (ASO and monospot) before initiating you on treatment. You will recover within a day or two of the medications since most throat infections, regardless of however severe they may be, lead to very good recovery. It is just the matter of time and use of the right medications. Get well soon
