can someone help ?!

I've been having some discomfort with my lady parts, it's red, puffy and itchy to the point where i cannot sleep and i been trying not tp scratch it. I noticed the dicomfort part this saturday night and it got worse from there. last night i shaved it thinking it might be because of the growing hairs but when i was washing myself the soap was burning me. Has anyone had these 3 symtoms before ?? if so, what did you do to make it better? how long did it last??
