I wonder if any advice can be given?

At the moment,i have been having trouble swallowing, my throat,on left side is sore,my jaw is hard to open/close,and pain when u touchthe left side of jaw. My tongue has developed 'tares'/gaps on the top,1 is sore to touch and swollen. An ulcer is on the rite hand side,towards the back of tongue. I am,heathwise 'run down' at the mo,and have started a course of iron(galpher)tablets. I do have denatl probs and am attending a dentist for treatment. Have i just got the start of a bad cold? I have alot of sadness going on as well,so have been crying alot.
