Seeing a worm in your stool, along with your symptoms, strongly suggests a parasitic infection like pinworms, which antibiotics like Metrogyl or Ciplox TZ do not cure. Frequent use of these medications can also disrupt your gut health. Please don't worry, as these infections are very treatable. I highly recommend consulting a doctor for a stool test to identify the exact parasite so they can prescribe the correct deworming medication.

It is very common for little ones to experience frequent, foul-smelling stools after taking antibiotics and metronidazole (Metrogyl). These medications can temporarily disrupt the healthy bacteria in your son's gut, leading to antibiotic-associated diarrhea or temporary difficulty digesting milk sugars (lactose). Since this has lasted for three weeks, his gut lining likely needs some time to heal. Please ensure he stays well-hydrated. I highly recommend consulting his pediatrician, who can evaluate if a probiotic, stool test, or temporary dietary change is needed to help his gentle tummy recover.

It is actually quite common and harmless for Metrogyl (metronidazole) to turn your urine a dark or reddish-brown color; this will resolve once you finish the medication. The mild burning could be due to mild dehydration from diarrhea, so please increase your fluid intake. While your past gallbladder removal is likely unrelated to these urinary symptoms, if the burning worsens, or if you develop a fever or back pain, please contact your doctor to rule out a urinary tract infection.

Moving teeth when you have lost half of their supporting bone can cause them to loosen or fall out, so "fast" or DIY aligners are not safe. Your use of Metrogyl DG gel (metronidazole/chlorhexidine) shows you are actively managing gum issues, which is excellent. Right now, the most important step is to work with a periodontist (gum specialist) to stop further bone loss and stabilize your gums. Once your bone health is completely stable, they can discuss safe, gentle cosmetic options with you.

It is very common to experience a localized allergic reaction (contact dermatitis) to ingredients in topical treatments like Candid V gel (clotrimazole) or Fucidin ointment (fusidic acid). While your oral antihistamine (cetirizine) and antibiotics (cefixime and metronidazole/Metrogyl) successfully cleared the visible rash, the persistent severe itching can occur because the delicate vaginal tissues remain highly sensitized and irritated, or the underlying infection was not fully resolved. Please stop using the suspected topical products immediately. Your next step should be to consult your gynecologist or a dermatologist.

Since you have finished your courses of Metrogyl (metronidazole) and Mebex (mebendazole), the itching could be due to temporary skin irritation, a mild yeast imbalance caused by the antibiotics, or surviving pinworm eggs if that was the initial cause (which often requires a second dose of mebendazole after two weeks). I gently recommend keeping the area clean and dry, avoiding harsh soaps, and speaking with your doctor. They can easily identify the cause and suggest a soothing cream or appropriate follow-up to help you feel better soon.
