Hi. Thank for your query. Noted the history of spots like things around anus and round the vagina area, skin is sore and red hence causes stinging while urinating, hurts o sit down too, wants to know whether double base cream would help. With the history you have provided, this looks to be serious problem in the sense that this looks to be STD or something like uncommon infection. Hence I would advise you the following: Consult your Gynecologist or a General Surgeon to have a clinical examination, detailed history , actual examination to get the correct diagnosis, ask for investigations of blood, urine, stool. Apply locally Liquid Povidone Iodine. A course of an antibiotic and metronidazole and probiotics. Complete the course of treatment till you are cured. No sex till then if you have a partner and get his too investigated and treated as required. Take plenty of oral fluids.
