HI. Thanks for your query. Sorry to know that some Doctors may not be having a proper clinical / physical examination. But in a normal circumstance a Doctor can get far more information and a probable diagnosis by your good, detailed history alone. I am sorry , here too I could only read what you have mentioned and going to comment upon the history you have provided. Well, back to your problems. The multiple ulcers you have could have been due to aphthous ulcers and the cause is not known . The probable cause is GI (gastro-intestinal) disturbance. and this is always tried to correct with appropriate antibiotics and metronidazole. So continue the medicines as advised by your Doctor and Vitamin A and D has to be taken in therapeutic dosage. Too much swelling of the upper lip looks to be due to either angio-neurotic edema or infection of the ulcer. The lips have a different tissue structure so the edema can be far more severe than other places in the body. You may need oral steroids for early settlement .
