A bump on your knuckle, especially one that's painless unless aggravated, could suggest several possibilities, including a ganglion cyst, a lipoma, or a small bone growth. These types of bumps are often benign (not cancerous) but can sometimes cause pain if they are hit or pressed. Since you’ve had it for six months without significant discomfort, this is encouraging; however, it's good to be aware of changes in size, shape, or any emerging symptoms.
What to Know About Your Bump:
-
Ganglion Cyst: This is a fluid-filled sac that often forms near joints or tendons. They are typically harmless and can resolve on their own but can cause discomfort if irritated.
-
Lipoma: These are soft, fatty lumps that develop under the skin and are usually painless. They don't require treatment unless they get larger or cause discomfort.
-
Bone Growth: Occasionally, a bony prominence can develop in response to trauma or wear, but this is less common.
Next Steps:
-
Monitor the Symptoms: Keep an eye on the bump for any changes. Note if it becomes larger, if you experience pain more frequently, or if any redness or swelling develops.
-
Protect the Area: To avoid pain, be cautious around the bump. Try to minimize hitting it against hard surfaces when possible.
-
Consider Ice Treatment: If the bump begins to feel more uncomfortable, applying ice for 15-20 minutes several times a day may help reduce any potential swelling.
-
Self-Examination: Gently assess the bump. Is it movable, or does it feel attached to the underlying bone? A movable bump is often less concerning.
-
Research Conservative Treatments: Over-the-counter pain relief like acetaminophen or ibuprofen can help if the area becomes painful.
If the bump starts to grow, becomes significantly painful, or if you develop any new symptoms, you might consider seeking advice from a healthcare provider for further evaluation.
Remember, the vast majority of bumps like these are benign and manageable with attention.

Infrequent Bowel Movements While Following a Diet: Is It Within the Norm?
Profile: Male, 6 feet tall, weighing 230 pounds. --- Throughout the year 2024, I committed to the One Meal a Day (OMAD) lifestyle, consuming approximately 1500 calories from Monday to Friday. On Fridays, I increased my intake to around 2500 calories, and about 2000 calories on Saturdays. Sundays saw a further reduction with approximately 1300 calories, and I also included around 1400 calories from alcoholic beverages weekly. This regimen led to substantial weight loss over that year. In 2025, I maintained a similar dietary structure, though I indulged in occasional snacks. Now, in 2026, my daily caloric intake has dropped to about 1300 calories on weekdays, ramping up to 2700 calories on Fridays, 1700 on Saturdays, and 1300 again on Sundays, complemented by roughly 1500 calories from alcohol over the weekend. However, I am experiencing bowel movements infrequently—every 3 to 5 days—though it tends to average out to 4 to 5 days. There are some instances where it occurs on the third day. Interestingly, I do not encounter constipation or discomfort during this period. On the days I do have a bowel movement, I may feel slightly bloated in the morning, but the feeling passes after I go. About nine months ago, I consulted with a physician regarding this issue, and after the requisite blood tests, the only abnormal finding was low folate levels. The doctor did not express concern regarding my infrequent bowel movements in relation to my dietary habits. As for the consistency of my stools, I have experienced small, pebble-like stools on one occasion, but most often, my bowel movements are normal. I seek your thoughts on this situation. Does this frequency seem typical considering I am following a significant caloric deficit with just one meal a day? Additionally, I completed a FIT test three weeks ago, which returned negative results, helping to rule out any serious concerns.
Is Low Oxygen Level a Cause for Concern?
Hello everyone, I'm a 23-year-old female, standing at 5'5" and weighing 81 kg. I’m currently prescribed 150mg of sertraline for managing anxiety and depression, along with 30mg of Elvanse for my ADHD. Recently, while reviewing my health data collected from my Apple Watch, I found that my blood oxygen saturation was recorded at 89% on the morning of January 30th, with my heart rate at 104 beats per minute. Typically, my oxygen levels hover between 97% and 100%, and in a relaxed state, my heart rate tends to be around 80 to 95 bpm. During the time I registered these troubling stats, I was seated in a car with a friend who was driving us to a shopping trip. I distinctly recall feeling extremely breathless, dizzy, shaky, and somewhat nauseous. Initially, I attributed these sensations to a panic attack, as this is not an unfamiliar experience for me. However, seeing such a low reading for my oxygen level has left me feeling quite anxious. Should this be a cause for concern? Over the past nine years, I’ve consulted with doctors regarding various heart-related symptoms, such as palpitations and chest pains, only to be reassured that they were likely just related to anxiety. I underwent a 24-hour ECG about two years ago, but the results were unremarkable, as I didn't experience any notable incidents while it was being monitored. Could this situation be indicative of an underlying heart condition? How can I effectively communicate my concerns to my physicians if I feel this is something that warrants further discussion?
Challenges Following Appendectomy
Approximately six months back, I underwent an appendectomy due to inflammation of my appendix. Initially, my recovery seemed successful; however, I have recently started encountering a painful, jabbing sensation in the same area. This discomfort is particularly noticeable during physical activities, along with intermittent cramping and mild breathlessness. Could these symptoms be solely attributable to adhesions, or might there be alternative explanations for what I’m experiencing? For context, I am a 19-year-old female.
Is Getting a Tetanus Shot Necessary for Me?
Profile: 24 years old, 5 feet 4 inches tall, 180 pounds, no medications or smoking history, injury date: February 14, involved my heel. Identifying as FTM, currently not undergoing hormone replacement therapy. This past Saturday, while preparing food in my partner’s kitchen, I accidentally stepped on a sharp piece of glass. The shard was cube-shaped, approximately 1.2 mm on each side, and featured a sharp edge about 0.25 mm in height. It penetrated my heel, which I managed to remove, resulting in a minor bleeding, roughly a drop or so. Initially, I was concerned that a fragment might still be lodged in my foot due to a lingering stinging sensation; however, two days later, I don't sense any presence of glass. I thoroughly cleaned the area with alcohol shortly after the incident and applied Neosporin about 20 minutes later. Concerned for my well-being, I reached out to my doctor for advice. He stressed the importance of getting a tetanus shot promptly, mentioning that I am three years overdue. Is this recommendation warranted? After experiencing an allergic reaction to a COVID booster a few years back, I’ve become quite apprehensive about receiving vaccinations again. My physician advised that I should get the shot by the end of the day, but I'm feeling dehydrated, which I understand could heighten my risk of a reaction. Can I choose to forgo the tetanus shot this time? If it's necessary, how much additional time might I have? The weather is quite poor today, and I would prefer not to drive in such conditions. Thank you for your assistance!
Will I Receive Proper Medical Attention If I Injure Myself?
I feel like the medical professionals no longer take my physical complaints seriously; they often attribute my problems to mental origins. Recently, I was bitten by a bat, and I suspect it may have transmitted a parasite to me. If I were to injure myself in the stomach and summon an ambulance, do you think they would examine me thoroughly? I imagine they would need to, but would they be capable of identifying if I have a parasite or if I've contracted rabies or something similar? I appreciate your insights.
