The fact that you are describing the rash you have as hives
and the fact that it seems to be coming and going over various areas of the body all do in fact go along with a diagnosis of hives, or urticaria as they are officially known.
Urticaria are usually associated with the body's exposure to some food or environmental allergen or to a common cold virus. After the exposure, the hives may come and go for a few days to week, and then should go away. In the meantime, you can control the symptoms and the itching with an over the counter antihistamine medication like diphenhydramine. This is usually not a serious problem unless you develop more overt and worrisome allergy symptoms, such as swelling of the face, lips or tongue or wheezing or trouble breathing (in which case you should seek immediate medical attention).
Fortunately, neither Herpes, HPV, or ganglion cysts are associated with this kind of rash. Herpes can cause a skin rash, but it is usually painful and blistered and does not come and go like hives. If you do develop a herpes-like rash, you should talk to your primary care doctor
about this, as treatment is available.
