Hello, You are suffering from bladder infection. You took antibiotics for it but you are having stinging pain and discomfort on having sex with your partner. You are suggested to get urinalysis (R/E and C/S) done so that you can take the specific antibiotic. Take adequate amount of water and fluids. You can take Spasmol (spasmoproxyvon), one SOS when needed for relieve from pain and discomfort. Avoid any type of sexual activity for a couple of days. Yes, cold sores are contagious at the prodome stage. When blisters are filled with clear fluid cold sores spread easily, do not break the blisters. They get most contagious when they break and become open sores. The sore starts to dry out and scab over. It may crack or bleed. The sore is still contagious. When the sore begins to scab over and scab falls off, the area may look pink or red for a few days. The sore is no longer contagious once the skin heals. Genital herpes can cause pain, itching and sores in your genital area. But you may not have any signs or symptoms of genital herpes. If infected, you can be contagious even if you have no visible sores. Men and women can develop sores on buttocks and thighs, anus, mouth, urethra, etc. Women can develop sores in or on vaginal area, external genitals or cervix. You are suggested to get clinically examined by a GP/Gynae, get STD, tests for herpes done, if positive you will be treated with antibiotics and antivirals. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
