Itching by itself is indicative more of a yeast/fungal or bacterial infection. Truly you should have your symptoms checked out - all of those ailments can be tested by swab. A blood test doesn't necessarily define actual symptoms.
Looking at pics on the net does you no good. There wasn't a one that looked like my genital herpes outbreak.
Itching is a sign of many things, including herpes. HSV2 shows negative. However, two weeks is too soon to say its definite. The IGG test needs more time before its definite. Talk more with your doctor on Monday.
