Swelling and a Lump in My Thigh: Should I Be Concerned?

6/28/2025, 8:20:21 PMMale25-34

Last night, I experienced an alarming incident where my left leg suddenly went numb, followed by noticeable swelling and hardness. Given my family’s history of thrombosis, my mind raced with concern. Perhaps I was overreacting, but I made the decision to head to the emergency room. By the time I arrived and was evaluated, the numbness had improved considerably, and the swelling had diminished significantly. They performed an ultrasound on the area behind my knee and in my groin, concluding that there were no signs of thrombosis, which made me feel a bit foolish for coming in. Today, however, I've discovered a painful lump roughly 10 centimeters above my left knee, which is the same leg that swelled up yesterday. The discomfort resembles that of a bruise, and the bump feels somewhat like an enlarged vein. Notably, it isn’t warm or red. I’m beginning to wonder if this could simply be a varicose vein that wouldn’t require immediate evaluation, or if it would be wise to consult a doctor sooner than planned. My mother suggests I take one of her blood thinners until my appointment on Monday. Is it advisable to use her medication, or could that pose risks? To provide additional context: I am a 34-year-old female, non-smoker, standing at 170 cm and weighing 52 kg. I am white and live with Hashimoto's disease, for which I take NDT and LDN. This situation is unprecedented for me; I’ve only started noticing varicose veins after giving birth.

It’s understandable to be concerned about sudden leg symptoms like swelling, numbness, and the new lump you're experiencing. While your symptoms have improved since your emergency room visit, it’s essential to pay attention to any changes in your condition moving forward.

Explanation

The symptoms you describe, such as the swelling and development of a lump, could potentially be due to a few different causes, including varicose veins, hematomas (bruises), lymphatic issues, or muscle strains. Given your family history of thrombosis, it’s wise to be vigilant. However, since the ultrasound showed no thrombosis, it may indicate that a serious vascular issue has already been ruled out.

The lump you’re feeling could be related to changes in circulation or muscle trauma, especially since you noted that it feels like an enlarged vein and resembles a bruise. The fact that it’s not warm or red is reassuring, but it should still be monitored closely.

Priority Next Steps

  1. Avoid Self-Medicating: Do not take your mother's blood thinner without consulting your doctor first. Blood thinners can have serious side effects and should only be used under the supervision of a healthcare professional.

  2. Rest and Elevation: Give your leg some rest. Elevate it when you can, as this can help reduce swelling.

  3. Monitor Symptoms: Keep an eye on the lump and any new symptoms that arise. If you notice increased pain, warmth, redness, or if your limb feels increasingly numb or cold, seek medical attention sooner.

  4. Apply Ice: If the lump is painful, applying a cold compress can help reduce swelling and discomfort, but don’t apply ice directly to your skin—wrap it in a cloth first.

  5. Document Your Symptoms: Write down when you notice changes in the lump or any other symptoms so you can share this information with your doctor on your next visit.

  6. Consult Your Doctor: Since you have an appointment on Monday, continue with that, but if symptoms worsen or you have new concerns, don’t hesitate to reach out to your healthcare provider before then.

Remember, your body is your best guide; trust your instincts about your health, and please reach out if you feel uncertain as the situation develops.

Should I Be Concerned About My Swollen Occipital Lymph Nodes?

I’m an 18-year-old female experiencing some concerning symptoms. A while back, I was diagnosed with dermatitis, which resulted in small lesions on my scalp. Unfortunately, I have a habit of scratching them at night, and a few months ago, this led to an infection that required antibiotics for treatment. Currently, I’m noticing that the lymph nodes located at the back of my head are swollen, quite painful, and tender to the touch, especially when I move my neck. Should I seek immediate medical attention at the emergency room, or is it safe to wait until the morning? I’m also worried that this could potentially escalate to something serious like sepsis or meningitis. I feel quite anxious about the situation and would appreciate any guidance!

Understanding Cellulitis in the Breasts: Is It a Cause for Concern?

At 20 years old, I've noticed a cellulite-like appearance on my breasts and I'm feeling anxious about it possibly being a sign of cancer. My initial research online primarily led me to information about breast cancer, which heightened my fears. However, the images I came across didn't match what I'm experiencing. The areas in question simply resemble standard cellulite, and I can’t recall if this has always been present or if it’s a more recent development. I did have some breast growth after beginning birth control about six months ago, but I doubt that the changes are significant enough to result in cellulite, especially since I haven't observed any new stretch marks. Aside from this concern, everything else about my breasts seems perfectly normal. They are symmetrical, the nipples appear healthy, and I don’t detect any lumps, pain, or signs of inflammation. I'm looking for insight into whether having this condition in my breasts is common, or if it could possibly indicate a more serious issue like cancer.

Unpleasant Odor Challenges

I’m a 22-year-old female and recently underwent testing for sexually transmitted infections, all of which returned negative results. However, I do have a history of herpes. For quite some time now, I’ve been experiencing a fishy odor that I can't seem to shake off. After consulting with my healthcare providers, they suspect I might have polycystic ovary syndrome (PCOS), although I am not facing infertility issues. Currently, I am pregnant, which seems to exacerbate the odor. Although my family reassures me that I don’t have a foul smell, I am convinced that it’s noticeable to others. Despite my efforts to maintain hygiene—I can shower up to four times a day—the unpleasant scent persists. To combat excessive sweating, I have even resorted to not wearing underwear. I’m covered by Medicaid and regularly visit my doctor, especially now that I have a one-year-old daughter to care for. Constipation has been a recurring issue for me; I’ve always found it challenging to have regular bowel movements. I also notice a connection between my breath and the odor, indicating that there may be an underlying problem. This situation is truly distressing and is negatively impacting my life. I have trouble securing employment due to my embarrassment about the scent. I am knowledgeable about proper showering techniques—I use wet wipes and even add bleach to my laundry—but nothing seems to alleviate the situation. It has come to my attention that my neighbors might also be affected by the odor. As a child, I experienced numerous urinary tract infections that might be related to past trauma. I’m at a loss and in dire need of assistance as I navigate this troubling issue.

Concerns Regarding HTLV and Ongoing Symptoms

On October 11, 2024, I engaged in unprotected intercourse with a new partner, and we both have herpes simplex virus type 2 (HSV-2). The following morning, I experienced unusual sensations in my vaginal area. Subsequently, my partner underwent testing on October 12, 2024, which showed negative results for: - Chlamydia - Gonorrhea - Hepatitis A - Hepatitis B - Hepatitis C - HSV 1 - HIV - Syphilis By the end of that week, I faced severe irritation, inflammation, and painful urination. My physician prescribed Metrogel, which alleviated some of the burning sensations, but the irritation lingered. In November 2024, I was diagnosed with infections caused by Mycoplasma hominis and Mycoplasma genitalium. My partner tested negative for Mycoplasma genitalium. I completed the treatment for both infections by April 6, 2025. On May 5, 2025, during a visit to my OB, I underwent swabs for various STIs and also submitted a urine sample. The results indicated no signs of: - Chlamydia - Gonorrhea - Syphilis - Mycoplasma genitalium - Mycoplasma hominis - Ureaplasma - HIV - Hepatitis A - Hepatitis B - Hepatitis C - Trichomoniasis - Bacterial vaginosis (BV) including Atopobium vaginae, BVAB 2, Megasphaera 1 - Candida albicans - Candida glabrata The urine analysis was generally normal, with the exception of ketones, likely due to fasting. A genital culture revealed a minor presence of Group B Streptococcus, which was successfully treated with amoxicillin. Despite these treatments, I continue to experience pelvic pain, ongoing vaginal discomfort, and recently, a small quantity of white-gray discharge without any odor. Two weeks after completing the amoxicillin treatment for Strep B, I took an Evvy test, which showed virtually no beneficial bacteria and complete disruption: - 70.95% Gardnerella Swidsinskii - 12.35% Gardnerella Vaginalis - 5.43% Megasphaera Lorne - 4.56% Gardnerella Leopoldii - 4.16% Prevotella Bivia - 1.37% Gardnerella Piotii - 1.19% other Gardnerella I intend to begin a course of boric acid for 5 to 7 days, followed by another 5 to 7 days of Metrogel, and then I plan to use probiotic suppositories. In addition, I have growing concerns about HTLV, which I only recently learned about from an online conversation. This STI is known to potentially lead to neurological symptoms. Since late February, I've been experiencing symptoms on my right side including swelling and tingling in my leg, tightness in my clothing, and by April, sensations of coldness, heaviness, and numbness. Emergency room visits have ruled out blood clots and stroke through normal blood tests, ultrasounds, EKG, chest X-ray, and CT scans. Symptoms have intensified throughout May and June and now include tingling and numbness in my right arm, pressure behind my right eye, tightness in my breathing, muscle twitching, balance issues, mild swallowing difficulties, and intermittent pressure in my right ear. Additionally, I now feel cramps and tightness in both calves. A neurologist has ordered MRIs of my brain, orbits, and cervical/thoracic spine with and without contrast; all came back normal, showing no evidence of stroke or multiple sclerosis. I have an EMG scheduled for this week. Furthermore, I have undergone a comprehensive immunology and thyroid panel (both normal) as well as a gastrointestinal workup including colonoscopy and endoscopy (results normal), and RA/ANA testing which was negative. I have consulted my immunologist about the possibility of testing for HTLV and am currently awaiting further guidance. I was previously unaware of this condition and now it has become a source of concern for me.

Concerning Raised Lesion on My Child's Leg – No Pain but Itchy – Should I Be Worried?

A 10-year-old girl has developed a raised lesion on her leg that has persisted for three weeks. I only discovered it today. She reports that while it itches, she hasn't experienced any pain. The elevation of the lesion is notable and, to my knowledge, she has never had any moles or skin irregularities on that leg before. It appears that the lesion is detaching from the surrounding skin on one side, which likely caused it to bleed when she scratched it. I'm uncertain if I should take her to the emergency room or wait until Monday to consult her pediatrician. Although it resembles a mole, she did not previously have one, and I'm aware that moles do not typically grow to this size in just three weeks. There are no signs of pus or infection, but I'm left perplexed about what this could potentially be.
