Thanks for your question and concern. It sound like you have been affected by a local irritation and this has led to enlargement in size, itching around the genitals, burning sensation and the bump in the inner side of the thigh. The reason for the local irritation to arise in your body may be due to the shaving and this had resulted in dermatitis. The other common causes of the symptoms seen in your body may be due to the folliculitis. The folliculitis is also known as the yeast infection. It is a bacterial growth on your skin due to sweat or due to the hair follicles present on your skin. During the time of shaving it will trap the bacteria in the ingrown hair follicles. If this is the reason for your problem, it can be easily solved by the use of diflucan. This is an antifungal medicine and is very effective in curing such problems. The symptoms seen in your body is not from a herpes infection as if it is due to the herpes infection the vesicles would feel extreme pain, tingling or the burning sensation according to the development of the vesicles. A different form of chlamydia which is popularly known as the lymph granuloma venereal (LGV) can affect the body in the same way as you have described. The LGV occurs by the chlamydia trachomatis bacteria and it would invade the lymphatic system of our body and cause the irritation and the swelling effects in our body. The first approach of the disease would be painless, genital ulcer after one to two weeks from its first approach would resolve within a time period of few days. But after the first approach the disease would come with its second attack and affect the lymphatic vessels and nodes and results in a stage of swelling, redness and all. With the proper treatment by the use of medicines like the erythromycin or with doxycycline the infections can be cured quickly. For the final concern about your hair growing back double, it does not make any medical sense. If the symptoms persist or worsen, you should immediately approach a licensed physician and tell all your problems facing by you and get necessary medical support. Take care.
