Hello,
Welcome to icliniq.com.
The symptoms sound like some vaginal infection. Vaginal infection is transmitted during sex (so the partner is the source), so both have to be treated at a time, or else you will get infected the next time of sex. You may have white or yellow, or grayish discharge with or without itching, foul smell, pain at the beginning of sex due to dryness (as the lubrication will be reduced) late towards the end when a fully erect penis touches the innermost vagina due to inflammation of the structures around the uterus with pain radiating to the back and thighs. Associated with infection, the bowel movement is also affected. There are also features of gastritis.
Bleeding of periods will be thicker and darker, with clots and fleshy masses like, and may smell bad; there are more days with spotting after the periods, too. When you have an infection inside the uterus, the blood flow increases as the inner lining is inflamed, and the blood mixed with the inner lining of the uterus forms a thick, doughy, or fleshy mass. As the healing of the lining is not complete, it keeps spotting, or you have blood-stained discharge. Pain is throbbing even before and lasts after periods are over, too. Usually, the infection is mixed and not just due to yeast fungus. There will be a family of aerobic and anaerobic bacteria, which cannot be detected on culture. When one is treated and cleared, the other will grow, and if not fully treated, it will regrow. Before starting the treatment, confirm that you are not pregnant. I suggest you and your partner consult your specialist doctor, discuss with them, and, with their consent, take the medicines mentioned below.
1. The Fluconazole tablet is 150 mg, and there is only one tablet with no repetition after lunch.
2. Tablet Azithromycin 1 gm stat only one tablet with no repetition one hour before food.
3. Tab Secnidazole Forte, two tablets stat with no repetition after dinner.
All these will be done on the same day by both of you. I suggest you can also have capsule Doxycycline 100 mg twice a day for one week, vaginal wash with V Wash (Lactic Acid Formulation), or similar cleanser twice a day and a vaginal pessary. Also, capsule Clingen Forte (Clindamycin, Clotrimazole, and Tinidazole) or Candid-CL (Clindamycin Topical and Clotrimazole Topical) or Cansoft-CL (Clindamycin and Clotrimazole) once at night for five nights. Your partner can have a local application of an antibiotic and antifungal cream Candid-B (Beclometasone Topical and Clotrimazole Topical) or Candiderma cream (Beclometasone Topical, Clotrimazole Topical, Neomycin Topical) or Lobate GM (Clobetasol Topical, Miconazole Topical, and Neomycin Topical) on the penis twice a day after wash for seven days.
Do not have sex until the infection is fully gone.
Thank you.
