Why Does My Saliva Have a Fishy Odor?
I'm an 18-year-old female with no existing health conditions, not on any medications, and I don't smoke or drink alcohol. Lately, I've been grappling with persistent post-nasal drip that seems to happen constantly throughout the day. To alleviate it, I often try to expel the mucus buildup since swallowing it can lead to discomfort in my stomach, causing strange rumbling sensations. What’s particularly concerning is that I’ve recently started to notice a very strong fishy odor emanating from this thick, clear liquid that I cough up. This is perplexing to me, especially since my regular saliva doesn't have any smell at all. Can anyone offer insight into what might be causing this fishy scent?

Experiencing a fishy odor in saliva during persistent post-nasal drip can be concerning, but it often has identifiable causes. This might result from mucus accumulation, which can interact with bacteria in your throat or sinuses, leading to unusual smells. While it’s good to be attentive to your body’s signals, many cases can be managed with some self-care strategies.
Explanation
Post-nasal drip can occur due to allergies, sinusitis, or even dietary factors. When mucus accumulates, it can provide a breeding ground for bacteria, sometimes causing a fishy smell. Additionally, certain foods (like fish or spices) or even dehydration might influence the scent of your saliva.
Next Steps
-
Stay Hydrated: Drink plenty of water throughout the day. Hydration can thin mucus and may help reduce post-nasal drip.
-
Saltwater Gargle: Gargling with warm saltwater can soothe your throat, reduce mucus, and may help alleviate any unusual odors caused by bacteria.
-
Monitor Your Diet: Pay attention to any foods you consume that might contribute to the smell. Spicy or fishy foods can influence saliva odor.
-
Nasal Irrigation: Consider using a saline nasal spray or a neti pot to help clear your nasal passages and reduce post-nasal drip.
-
Keep a Journal: Track the occurrence of the fishy smell and any associated symptoms. Noting any patterns could be helpful in determining specific triggers.
If the odor persists despite these measures or if you develop additional symptoms like fever, facial pain, or changes in taste, you might need to reassess. In the meantime, focus on these practical self-care steps. Let me know if you need further information or help!

Experiencing a Shock from an Electrical Outlet
I am a 19-year-old female, standing 5 feet 8 inches tall and weighing 135 pounds. Currently, I’m residing in a hostel and was about to connect my phone charger to the outlet next to my bed. In the darkness, I accidentally came into contact with both metal prongs using one finger. A sharp burning sensation shot through my hand and up my arm, causing my entire body to tense up, particularly in my legs, prompting me to drop the charger immediately. My fingers experienced tingling and slight stiffness for a short while, but they have since warmed up. Now, I find myself unsure if I feel lightheaded or if my heart is racing oddly, or if this is simply a reaction of anxiety or adrenaline. It’s late—around 1 AM—when I should be asleep, especially since I have to catch a train in the morning. However, I'm concerned about whether it's safe for me to rest after this incident.
Concern About Chest Bump
Greetings, I’m a 25-year-old female reaching out for some advice. I’m uncertain whether this issue requires urgent medical attention, but I’ve noticed a small elevation, which I suspect could be an ingrown hair, positioned near my areola. It has appeared red and slightly swollen throughout the day. After work, I applied ice to the area and decided to remove my bra since it felt a bit constrictive. I’m particularly worried as the redness has expanded to around the size of a half dollar, which seems rather distant from the actual site of discomfort. If necessary, I can send a direct message with a photo, although I would prefer not to share it publicly. I appreciate any guidance you can offer. Thank you!

Understanding the Connection Between Hiccups and Certain Foods
I’m a 25-year-old male, weighing around 140 pounds and standing 5'9" tall. I don’t smoke and consume alcohol infrequently. I've never been diagnosed with any medical conditions and don’t take any medications. In a recent episode of Brew, I learned about hiccups and how they occur. The show indicated that certain foods can irritate the phrenic nerve, leading to hiccups. Interestingly, I don’t experience hiccups from typical triggers like alcohol or carbonated beverages. However, there are specific items that consistently cause this annoying reflex, particularly biscuits and boiled eggs. When I start hiccuping after consuming these foods, it almost feels like they get lodged in my throat or descend very slowly. I’ve noticed that eating quickly seems to trigger them even more rapidly, yet even when I eat slowly, the issue persists. What could be the reason behind this peculiar response to these specific foods?
