Your etiology is not completely consistent with OC. I can't recall any of us having vomiting and most of us never have pain. In fact, OC is, by and large, a stealthy disease. Enlarged, swollen and tender lymph nodes are also consistent with infections. Your discharge is another clue. Never the less, you should still follow Cheryl's advice and make an immediate appointment with an ENT and resolve whatever the issue is. Take a deep breath...
