I had a cold sore and then it healed and i got another and a canker sore at the same time and now seem to be getting another cold sore near the other.

Fever Blister/Stress: With your diagnosis profile and the symptoms you are having now it may be wise to use suppressive therapy for fever blisters. That would entail taking a medication daily for a while ....But it is worth discussing with your doctor to decide on episodic or suppressive therapy.

Underlying Sickness?: When you get a combination of oral sores like that right in a row, it's often an indication of an underlying illness. It can be something simple like poor diet, high stress, or poor sleep, or it can something more serious. In either case, you could benefit from seeing a doc and getting a physical/check-up. If there's something else wrong which is affecting your immune system, you should find out.
