Should i go see my doctor now? or walk in clinic again?

Since you said sore red throat and trouble swallowing, I would think it's Strep, but the other symptoms make it hard to say. You might have Strep and something else, but I'm not sure. Try going back to your doctor and tell him to tell you what it is. You pay for that doctor, and you deserve to know what's wrong with you. Good luck, and I hope this all pes.
