01 / IDEAS WORTH EXPLORING ↗Ice cream can trigger two entirely different headaches, and most people confuse them. The sharp, 20-to-60-second "brain freeze" is a cold-stimulus headache caused by rapid cooling of your palate, and it is not a migraine.
Yes, IBS can make you feel sick all the time, and the reason is that irritable bowel syndrome is a disorder of gut-brain signaling rather than a structural disease, so symptoms can persist daily for months without any visible damage.
You should not wear contact lenses while a subconjunctival hemorrhage is actively visible or still expanding, because the lens sits directly over the injured vessels and raises the risk of irritation, microbial contamination, and delayed…
Yes, ibuprofen can cause gastritis and stomach damage. As a nonsteroidal anti-inflammatory drug (NSAID), it blocks the COX-1 enzyme that produces protective prostaglandins in your stomach lining.
Yes. Sperm collected for an intrauterine insemination (IUI) cycle can be used in an in vitro fertilization (IVF) cycle, but only after it passes through the same laboratory preparation step every IVF sample requires.
Yes, you can usually work out after getting a cavity filled, but the safe window depends on the filling type and anesthesia used: most people can train lightly within 2 to 4 hours after a composite or amalgam filling with local anesthetic,…
Irritable bowel syndrome does not damage the kidneys, and it does not cause kidney disease, but it can produce pain that feels like it comes from the kidney.
Yes, IV fluids can help some migraines, but mostly as a delivery vehicle rather than a cure.
Yes, you can use retinol on your lips, but only with a modified protocol: a low-strength formula (0.1 to 0.3 percent), applied at night, two to three times weekly to start, buffered with a ceramide balm, and never combined with lip…
Yes, most babies diagnosed with intrauterine growth restriction (IUGR) can be normal, healthy children.
Yes — but only if you had a hormonal IUD, and only as a temporary withdrawal effect, not a permanent imbalance. Removing a copper IUD does not disturb your hormones at all, because copper releases no hormones.
Yes, you can generally use triple antibiotic ointment while pregnant for small cuts and scrapes, because the amount of drug that crosses into your bloodstream from intact skin is very small.
Yes, you can use regular mupirocin ointment in your nose — but only when a clinician has prescribed it for that purpose, and only as a short, time-limited course.
Yes, you can use ketoconazole and clotrimazole together, and dermatologists sometimes do combine them, but almost never as two separate creams layered on the same patch of skin.
Yes, you can generally use salicylic acid while breastfeeding, provided you keep it to a limited area of skin and a low concentration.
Yes, you can usually take probiotics while on chemotherapy, but only with your oncology team's approval and only with specific, well-studied strains.
Yes, most healthy adults can take quercetin every day, and daily use is the schedule most studied in clinical trials.
Yes, you can usually use clindamycin while pregnant when a clinician prescribes it, because it carries a pregnancy category B rating from the FDA and is not linked to birth defects in human studies.
Yes, you can take probiotics and antibiotics together, and current evidence supports doing so with one critical caveat: separate the doses by at least two hours.
Yes, oxycodone and meloxicam can usually be taken together, because they work through entirely different pathways and do not chemically cancel each other out.
Yes, you can usually touch and hold your baby if you have shingles, because shingles itself is not contagious to people who have already had chickenpox or been vaccinated against it.
Yes, meloxicam and gabapentin can usually be taken together safely, because the two drugs work through completely different pathways and do not share a metabolic bottleneck.
Yes — you can take ibuprofen with guaifenesin safely in most cases, because the two drugs act on entirely different targets and do not share a metabolic pathway that would cause a dangerous interaction.
