What Should Be Done For Sore Throat Along With Severe Pain Causing Discomfort In Even Swallowing Saliva?

3 weeks now, sore to swallow, tender point on adams apple if I press on it 2-3 millimetres to the right from the centre, started after a works night where I was smoking and drinking, came home, slept, coughed alot the next day and noticed a small nae tiny amount of blood after I cleared my throat once and spat in the sink, no coughing since just discomfort from the point of pain and sore when swallowing saliva, not so sore when I eat though ?!. When I wake up in the morning it is not so bad but seems to get worse as the working day progresses. No cough or strep ,flu, cold symptoms. Now getting very concerned as my father just died from Cancer (Prostrate and bladder). Thoughts plaese ?
