The best way to find out if it's herpes is to get a swab test within 24-48 hours after the symptoms appear. Just remember that swab cultures are notorious for false-negative results, so if it comes back negative it doesn't necessarily mean you don't have it. A positive result is virtually always accurate though.
I think you have reason enough to be concerned and want some solid testing done by your doctor, since your last partner had it. Was it type-2 that this person had? If so, and if it was more than 3 or 4 months ago since the symptoms started, get your doctor to order a POCkit test, which tests specifically for type-2 and is inexpensive and fast in its results. If you test sooner than that it could come back as a false negative and you won't know for sure.
Herpes can look very different from one person to the next, so doctors don't always recognise it on sight alone. If this doesn't tell you anything for sure, get your doc to refer you to a dermatologist. It's obviously *something* and may or may not be contagious, but you want to be careful with it in any case.
Good luck! Let us know how you make out.
