Persistent coughing

Still went to work despite the cough and runny nose. Left early at 0730. Coughing has became worst and throat hurts a lot. Still can't feel stomach. Just ate some bread and some lean pork meat congee as lunch and dinner. At night, ate boiled cauliflower and celery. Still burping but does not feel so nausea now. Felt a lump and soreness in the throat so thinks it is phlegm but can not be coughed out so kept on coughing to try to cough the phlegm out. Got a paper cut beside my finger nail on the right of my right index finger. Not fatal but annoying cos it is difficult to heal and will keep tearing apart and seep a little blood now and then.
