Would i be able to feel herpes on vaginal wall? what would it feel like? and if so would it go away in 4 days?

See below: If you have not had genital herpes before(primary infection) the lesions would be very painful to touch and you would often have vaginal pain, pain on urination and or vaginal discharge. Other symptoms might include fever, headache and swollen inguinal lymph nodes.The lesions would consist of a swelling with tiny blisters(vesicles) and ulceration. The swelling would last 2-3 weeks.

Not always: If the lesion is deep in the inside of the vagina you may not be able to fell the out break. Some have symptoms of fatigue and not feeling well at the to time of an out break. If you think you have a lesion and can't confirm it, I suggest you take medicine for it every day to suppress a possible out break. This is called daily suppressive therapy.
