Our expert says:
Coldsore, it sounds like it might be coldsores or maybe even aphthous ulcers. The problem is that I can’t really say without examining you first. Cold sores or fever blisters are cause by the herpes simplex virus type 1 (HSV-1) and you might have contracted it a while before the symptoms started.
As a matter of interest – there are at least 7 types of herpes viruses. Type 2 causes genital herpes, type 3 causes chickenpox and shingles, type 4 causes glandular fever, type 5 is cytomegalo virus and they’re not exactly sure what diseases are caused by type 6 and 7.
Good luck and let me know if you have more questions.
