What Could This White Spot Under My Tongue Be?
Greetings! I’m 32 years old and identify as a trans man, although I’m not sure if that’s particularly relevant here. I occasionally smoke weed, though I’ve been doing it a bit more recently—typically just one puff every few months or possibly a few times a week in the evening. Recently, I started experiencing discomfort in the frenulum area underneath my tongue. Initially, it was just a mild annoyance when I yawned, but as the days went by, the pain intensified (admittedly, I didn't treat my tongue kindly at first, which probably exacerbated the situation). I suspect that I might have slightly torn my frenulum while tackling a rather large sandwich last Thursday. The rough bread certainly scraped my mouth and left my palate feeling tender for a while. A couple of evenings ago, I noticed that the area seemed swollen, prompting me to be more careful, which seemed to help. The following day (yesterday), there was a noticeable improvement, but that’s when a white patch appeared for the first time. Today, the pain has significantly decreased, but the white spot has grown larger. I hadn’t done any saltwater rinses up until now because I don’t have any salt at the moment (I recently moved and, honestly, I’m not a huge fan of salt). I’m hoping this is merely a sign of healing skin, but after some internet searching (I know, not the best idea), I’ve come across information that this resembles Leukoplakia, which is quite concerning. My weed consumption is minimal and very infrequent, just one large puff here and there during the time leading up to this issue. So, I’m now turning to Reddit for some advice, which is probably the second worst thing you can do after googling your symptoms! My plan is to continue with saltwater rinses a few times daily and see a doctor if the situation hasn’t improved in about a week.

It's great that you’re reaching out to understand your symptoms better! A white spot under the tongue, especially given your recent experiences with discomfort and potential irritation, can be concerning but can often be addressed through simple self-care measures. Let’s break it down.
Key Points
- The white spot may be due to irritation or injury to the tissue in your mouth.
- Leukoplakia is one possibility, but many cases of white patches are due to harmless conditions, especially after trauma.
- Keeping the area clean and observing changes is a vital next step.
Explanation
A white patch under the tongue can occur for several reasons, including irritation from food, mild infections, or healing tissue after trauma. Your recent injury from eating a rough sandwich could have caused irritation, leading to inflammation and the subsequent appearance of the white spot you observed.
Leukoplakia typically presents as white patches that cannot be scraped off and can sometimes indicate more serious issues, particularly in smokers and those who use tobacco. However, in your case, given the context of recent irritation and improvements in pain, it might simply be a response to the irritation rather than a serious condition.
Next Steps
-
Saltwater Rinses: Even though you’re not a fan of salt, a simple solution of warm water and salt can promote healing. If you obtain salt, try rinsing with this mixture 2-3 times daily. If you don't have salt, rinsing with plain water can also help keep the area clean.
-
Avoid Irritants: While the discomfort persists, try to avoid irritating foods (like rough bread) or substances (like tobacco) that might exacerbate the area.
-
Monitor Symptoms: Keep an eye on the spot over the next few days. If it starts to reduce in size and further discomfort diminishes, that’s a good sign of healing. However, if you notice:
- The white spot growing larger or not improving in a week,
- Bleeding,
- Severe pain,
- Or symptoms like difficulty swallowing,
This would be an indication to consult a healthcare professional for further evaluation.
-
Hydration: Stay hydrated; this can help your overall oral health and support healing.
Reassurance
It's understandable to feel worried, especially with the information you found online. Remember that many oral conditions are benign, especially after trauma. Make sure to observe how your symptoms progress, and don’t hesitate to seek help if you feel it’s necessary. You're doing the right thing by being proactive about your health!

Challenges with Vein Accessibility
At 23 years of age and standing 5 feet 10 inches tall while weighing approximately 198 pounds, I am faced with a frustrating issue regarding my veins. As highlighted in the title, I encounter significant difficulties when it comes time to either have blood drawn or to receive an intravenous (IV) line. The veins in my arms are located quite deeply and tend to roll under pressure, while the veins in my hands, which are more visible, are often quite narrow and hard to access. This is not merely a personal concern, as it is something that various nurses and phlebotomists have noted during their attempts to treat me, leading them to document this in my medical records. There was even a situation where a surgical procedure I was scheduled for had to be postponed until a more skilled phlebotomist was available to insert my IV. Most recently, I was unable to complete a CT scan that required contrast this morning due to the inability to locate a viable vein. Despite my efforts to prepare by hydrating thoroughly the night before and consuming an additional 32 ounces of water that morning, the medical staff struggled to find an accessible vein. They attempted several strategies, including applying heating pads to both arms and hands, and moving the tourniquet around consistently, but to no avail. Given that I have ongoing chronic health challenges, which now necessitate more frequent blood tests and IV access, I am eager to explore any proactive measures I could take prior to these medical evaluations—beyond simply increasing my fluid intake—to enhance the visibility and accessibility of my veins. Additionally, I would appreciate advice on specific requests I might make when setting up my appointments, especially in light of the recommendations I received from the technician who assisted me today. She suggested that it would be beneficial to inquire about locations where a nurse can perform an ultrasound for vein access, particularly for procedures requiring contrast imaging. However, I am uncertain how to approach this request. Moreover, I am unsure if it would be feasible to make similar arrangements for routine blood draws or when sedation IVs are required, especially since I will soon be undergoing extensive dental procedures. As someone on the autism spectrum who is highly sensitive to various stimuli, I have encountered worries from my dentists regarding the feasibility of safely administering dental work without sedation, even when using nitrous oxide or oral sedatives.

Understanding a Bump on My Arm
I am a 24-year-old female, and while cleaning the bathtub today, I observed that my right arm turned quite red as I scrubbed, which I assume is due to increased blood flow. Since then, my arm has been feeling somewhat fatigued and slightly sore. I tried to alleviate the discomfort by gently massaging my forearm, but during this, I discovered a peculiar bump that forms when I apply pressure. This bump disappears as soon as I stop squeezing, but it reappears whenever I press on that area. It's worth noting that this issue is present exclusively in my right arm.
