Bump Behind Ear: Seeking Advice
I am a 21-year-old female with no previously diagnosed health issues. I occasionally use nicotine through vaping but do not consume alcohol or any illicit drugs. I have been using a Nexplanon implant in my left arm since November 24. For more than a week, I've noticed a sizable lump forming behind my ear. It first caught my attention on Sunday, June 30, and since then, its size has increased. Initially, it appeared as a small bump near my earlobe, but shortly afterward, a larger lump emerged, and now it feels like a single large mass. This bump is very tender and sensitive when touched. It resembles a blister, yet it has a solid consistency as well. I'm worried because it continues to grow, and it's been over a week since I first noticed it. I plan to contact my general practitioner to arrange an appointment, but in the meantime, I would appreciate any thoughts or suggestions regarding this issue.

A growing lump behind your ear that is tender and resembles a blister can be concerning, and it's wise to reach out to your general practitioner. Here’s a breakdown of what might be happening and some steps you can take in the meantime.
Summary of Key Points:
- The lump could be caused by various issues, such as a lymph node enlargement due to infection or inflammation, or it could be a benign cyst.
- It's good to contact your general practitioner for a comprehensive evaluation, especially since the lump is growing.
Explanation:
The area behind your ear contains lymph nodes, which can swell due to several reasons, including infections (like colds or skin infections), more localized conditions like cysts, or other inflammatory responses. The tenderness and solid nature of the lump you describe are important signs to consider, but a physical examination is necessary for an accurate diagnosis.
Next Steps:
-
Monitor Other Symptoms: Keep an eye on any accompanying signs, such as fever, skin changes, difficulty swallowing, or any new lumps forming.
-
Pain Management: If the tenderness bothers you, over-the-counter pain relievers like ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) can help alleviate discomfort.
-
Avoid Irritation: Be gentle with the area; try not to poke or squeeze the bump, as this can worsen inflammation or cause infection.
-
Document Changes: Take note of any changes in size, appearance, or symptoms daily. This information can be helpful for your doctor.
-
Prepare for Your Appointment: When you see your general practitioner, share all relevant details, including when you first noticed the bump, changes in its size, and any other symptoms you've experienced.
These actions can help manage your current situation until you can see your doctor. Remember, you’re doing the right thing by seeking medical advice. Let me know if you have more questions or need further information!

Flattening of Breast with Intermittent Pain - Is Immediate Attention Needed?
I am a 44-year-old woman, measuring 5 feet 9 inches tall and weighing 180 pounds. I identify as Caucasian and reside in the United States. For the past couple of months, I have been experiencing a concerning change in my left breast, which has noticeably flattened on its outer section. At first, I didn't think much of it, but I have experienced pain on two occasions. The first instance was slight, while the second struck me late at night with considerable discomfort. Additionally, I've noticed that this breast seems somewhat denser than before, although there are no discernible lumps. My medical history is generally unremarkable; I am mostly healthy aside from carrying excess weight. It's worth mentioning that my paternal grandmother had a history of breast cancer. Currently, I am not on any medication. I’m in search of a physician but have found that the earliest appointment I can secure with a well-regarded specialist is in late August. In light of my symptoms, is this wait excessive? Would it be advisable to seek out imaging services sooner? Thank you for your insights!
Concerns Regarding Possible Stroke Symptoms
Recently, I’ve been feeling uneasy about potential stroke symptoms. Occasionally, I experience a tingling sensation in my face, a sense of tightness in my jaw, and every now and then, I notice that I slur my speech. While these instances are infrequent, they are noticeable enough to raise concerns, particularly following my use of a vape. I’m seeking guidance before jumping to any drastic conclusions about my health.
Should I Consult a Doctor Regarding This Bruise?
I’m a 20-year-old assigned female at birth, and although specifics about my height and weight may not be crucial, I do have hypermobile Ehlers-Danlos Syndrome (hEDS). Recently, I noticed a peculiar mark on my chest. Upon closer inspection, it appears to be a hickey accompanied by a noticeable bite mark, and interestingly, I don’t have any sensation in that area. This injury occurred approximately two days ago, and initially, I felt a lump beneath the skin, which disappeared by the following day. I can’t recall any red or white spots present at the time of the injury or afterward, but if they existed, they seem to have faded now. I’ve read that those symptoms may indicate a cause for concern, particularly with conditions like blood blisters or human bites. However, I don't think the skin was broken. I’ve been following the standard care recommendations for bruises and human bites, such as antiseptic cleaning and applying ice. My question is whether I should seek medical advice regarding this bruise. How long should I monitor it before becoming alarmed if it doesn’t heal? I assure you, I’ll avoid getting bitten in places where I lack sensation in the future!
Detecting Arthritis Symptoms at Age 21
I am a 21-year-old trans man (assigned female at birth), standing 5’6” and weighing 119 pounds. To provide some context, a little over two years ago, I experienced a fall that resulted in my tailbone hitting the stairs quite forcefully. Since that incident, I have encountered persistent pain originating from my tailbone and extending to my upper back. Recently, after receiving an x-ray through my primary care physician, it was revealed that I have "minimal degenerative endplate changes at L4-5" and exhibited "mild degenerative facet disease at the lumbar-sacral junction." My doctor indicated that these findings are indicative of arthritis and suggested that I pursue physical therapy. Following this, I consulted with a pain specialist who did not convey a significant concern regarding my situation and opted not to conduct further x-rays. This leaves me contemplating whether it might be wise to seek a second opinion from a spine specialist. Notably, arthritis is present in my family, with my mother suffering from severe cases of it. Also, I underwent a hysterectomy in August 2024 and am currently undergoing testosterone hormone therapy. I can’t help but wonder if the changes seen in my lower back are related to the injury I sustained to my tailbone.
Persistent Sore Throat? Here's What to Consider
As a 21-year-old female, I've been battling tonsillitis since childhood. A particularly severe episode in April required hospitalization. Recently, I noticed symptoms resurfacing. I was prescribed the typical course of Phenoxymethylpenicillin, taking 2 tablets four times daily for five days; however, my throat showed no signs of improvement. Now, I’ve switched to Clarithromycin, which I've been using for the past 48 hours, yet still, there's no relief in sight. While the appearance of my throat seems to have improved—those white patches have disappeared—the persistent pain is incredibly intense. This kind of prolonged pain is new to me; in the past, I usually felt a reduction in both the infection and discomfort after just a few doses of antibiotics. Does anyone have insights into what might be happening? This ongoing condition is really wearing me down, and the constant antibiotics are taking a toll on my stomach.
