Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Constipation can be a side effect of medication, however not very frequent. Other causes of constipation can be sudden change in dietary habits, excess intake of dairy, taking a low fiber diet, lack of physical activity, stress, hypothyroidism, diabetes, irritable bowl syndrome, eating disorders etc. For now take high fiber diet, do moderate workout, take walk after meals, drink plenty of water, take laxatives and stool softeners like Docusate, fiber supplements like Psyllium. You should eat every after 2 hours. Go to toilet on the same time every morning and try to evacuate your bowels as it can help in developing habit of regular bowels. As far as herpes is concerned, it can take up to 2 weeks for the symptoms to subside. For redness you can try Anovate ointment for relief. Hope I have answered your query. Let me know if I can assist you further. Regards.
