Seeking a Second Opinion on Ankle MRI Results
I’m doing my utmost to research my concerns online, but I’m struggling to determine which findings are genuinely alarming and which may merely stem from my active lifestyle as an athlete. As a dedicated rock climber and mountaineer who enjoys long-distance hikes nearly every weekend, I decided to have an MRI after experiencing pain in my ankle accompanied by a noticeable lump. Although the podiatrist reassured me by saying there is a tear but that it’s not serious, I am keen on obtaining a second perspective. Here are the MRI findings: **MRI RESULTS:** - The anterior inferior and posterior inferior tibiofibular ligaments remain intact. - Anterior talofibular, posterior talofibular, and calcaneofibular ligaments are also intact. - Both the deltoid and spring ligaments show no abnormalities. - There’s some attenuation and irregular shape of the peroneus brevis tendon in and just moving away from the retromalleolar groove, which raises suspicion of a partial-thickness longitudinal split tear. Additionally, there is mild peroneal tenosynovitis. - The peroneus longus tendon is intact. - Mild tenosynovitis is noted in the distal posterior tibial area, along with slight fluid in the flexor digitorum and flexor hallucis tendons. - Extensor tendons are intact. - Mild peritendinitis is observed in the Achilles tendon with a trace amount of fluid in the retrocalcaneal bursa. - The plantar fascia is intact. - A ganglion cyst measuring approximately 1.8 x 2.3 cm is located on the lateral side of the ankle, which aligns with the lump I noticed. This cyst likely originates from the sinus tarsi, which appears normal otherwise. - The os trigonum shows partial fragmentation and slight cystic changes in the posterior talus, usually associated with posterior ankle impingement, along with mild fluid accumulation in the posterior tibiotalar joint. - There are no signs of osteochondral lesions, and the tarsal tunnel appears normal. **SUMMARY OF FINDINGS:** 1. The ganglion cyst located laterally on the ankle measures approximately 1.8 x 2.3 cm, correlating with the detectable abnormality. 2. The inferred abnormality of the peroneus brevis tendon raises the possibility of a partial-thickness longitudinal split tear along with mild peroneal tenosynovitis. 3. Mild tenosynovitis is present in the posterior tibial area. 4. There is mild peritendinitis in the Achilles tendon. 5. Observations include partial fragmentation of the os trigonum and mild reactive changes seen in the posterior talus as associated with signs of posterior ankle impingement. I hope to clarify the significance of these results and the best course of action moving forward, hence my search for a second opinion.

It's understandable to seek clarity on your MRI results, especially as an active athlete. Your findings indicate some notable issues, primarily regarding the peroneus brevis tendon and a ganglion cyst, but also some other mild conditions. Let's break this down and discuss actionable steps.
Key Points:
- Peroneus Brevis Tendon: You have a suspicion of a partial-thickness longitudinal split tear and mild peroneal tenosynovitis.
- Ganglion Cyst: The cyst you mentioned is present and correlates with the lump you noticed.
- Other Mild Findings: There are recurring mild issues in the posterior tibial area, as well as mild peritendinitis in the Achilles tendon and observations related to posterior ankle impingement.
Explanation:
- Partial Tear and Tenosynovitis: A partial tear of the peroneus brevis tendon can cause pain and instability, which might impact your climbing and hiking. The associated tenosynovitis indicates inflammation in the sheath surrounding the tendon.
- Ganglion Cyst: This is a fluid-filled sac that can arise post-injury or from repetitive motions, and it's good that it has been identified, as it can sometimes cause pain or discomfort.
- Mild Tenosynovitis and Peritendinitis: These findings suggest some inflammation around the tendons, which can be common due to high physical activity.
Next Steps:
-
Symptom Management:
- Rest: Give your ankle a break, especially from activities that aggravate the symptoms.
- Ice Therapy: Use ice packs on the affected area for 15-20 minutes, several times a day, to reduce swelling and pain.
- Compression and Elevation: Consider using a compression bandage and elevating your ankle when resting to minimize swelling.
-
Monitoring Symptoms:
- Keep a daily log of your pain levels and any increases in swelling or other symptoms. This can help track changes over time.
-
Physical Therapy:
- A physical therapist can help strengthen the surrounding muscles and improve flexibility, which may alleviate some discomfort and support recovery.
-
Consider Further Evaluation:
- Since you seek a second opinion, I recommend consulting another orthopedic specialist who focuses on sports medicine. They can provide targeted insights and may suggest options like corticosteroid injections for inflammation, further imaging if necessary, or in some cases, surgical options to address the cyst or the tendon tear.
-
Activity Modification:
- Gradually reintroduce your physical activities. If certain movements exacerbate your symptoms, consider substituting them with low-impact alternatives until you feel more stable.
Conclusion:
While you do have some concerning findings, many of them are manageable with time and appropriate care. Prioritize rest and seek further evaluation for a tailored treatment plan, particularly as an active individual. Feel free to reach out with more questions or updates on your situation.

Recovery from a Second-Degree Burn
A 34-year-old woman, not currently taking any medications, recently sustained a burn from contact with an exhaust pipe a few days ago and is uncertain about the healing process. She has been diligent in maintaining cleanliness and dryness of the wound, using a fresh bandage once today during work, along with a light application of Aquaphor. Is there additional care she should be considering? Is the healing progress typical, or are there signs of infection?
Concerns About My Toenail Issues
As a 23-year-old female, I’ve been experiencing some discomfort related to my toenail. Recently, I noticed that the edge of my big toe nail was protruding slightly, which led me to trim it. It seemed like I wasn’t able to fully address the problem, leaving the surrounding skin feeling somewhat irritated. After a couple of days, the sensation wasn’t too alarming—just a minor irritation. However, while applying gel nail polish, I had to file my toenail down, unfortunately scraping against the already irritated skin with the nail file, and using acetone did not help matters. Consequently, the irritation worsened. For the past three days, my toe's appearance has remained consistent, and I have been diligently covering it with a band-aid during the day. I’ve been taking naproxen sodium (200mg) for pain relief, cleaning it while showering at night, and applying Neosporin, leaving it uncovered during sleep. Since reaching an irritated red state a few days ago, there hasn’t been any further deterioration, although I do experience discomfort when walking, especially if my foot is dirty or when I'm wearing closed shoes. I managed to drain some pus over the last two days, but currently, there seems to be nothing left. Initially, I suspected an ingrown toenail; however, after noticing something protruding, I realized it was exposed flesh, leaving me uncertain whether it’s actually an ingrown nail or merely highly irritated skin. I have not experienced any fever or skin rashes on my foot. If things do not improve, I’m contemplating a visit to an urgent care facility. I appreciate any insights you may have!
Seeking Clarity on Persistent Symptoms
Age: 28, Weight: approximately 163 lbs. Over the last year, I’ve been enduring a concerning range of symptoms including persistent bone and muscle pain, muscle spasms, discomfort reminiscent of sciatica, severe fatigue, daily headaches, a sore throat accompanied by swollen lymph nodes, and gastrointestinal disturbances like nausea and acidity, which have been particularly troubling. Recently, I’ve developed intense facial flushing, notably on my cheeks and nose. I’ve experimented with various medications, including Cymbalta and Lyrica, while avoiding SSRIs altogether, as well as methocarbamol and various muscle relaxants, but none have alleviated my pain. The muscle relaxants merely induce drowsiness, which is unhelpful during the day. Currently, I am prescribed bupropion, trazodone, and duloxetine (the latter at a daily dosage of 60 mg), despite the fact that none seem to provide significant relief. All my lab results have returned within normal ranges, with the exception of a positive ANA at 1:40, indicating speckled and cytoplasmic patterns, along with low CK Protein, low MCHC, and mildly elevated liver enzymes. Both X-rays and MRI scans have shown no abnormalities. I have explored numerous medications and strategies for managing Fibromyalgia, as that is the diagnosis being considered. Unfortunately, none have provided even slight relief, leading me to believe that there may be another underlying condition or possibly a comorbidity. Medical advice has now limited me to maximum doses of Tylenol and Ibuprofen for pain management. I have a scheduled appointment with a rheumatologist in October, so I’m holding out hope for answers. I would appreciate any insights. The possibility of lupus has been mentioned, but when I brought it up for further investigation, my concerns were dismissed. Thank you for your help!
Concern Over Ear Canal Bump
A 22-year-old male reports the emergence of a painful bump in his ear canal. He expresses concerns that it may be an infection and fears it could lead to episodes of vertigo. He is uncertain whether this is a trivial matter, akin to a pimple or boil, or if it necessitates further medical attention.
Persistent Cough for Several Months
Greetings, everyone! I’m a 27-year-old male, and I’ve been struggling with a lingering cough since early April. This all began after I caught a cold while visiting my father, who was later diagnosed with whooping cough soon after my visit. When I consulted my primary care physician in mid-April, he noted that my lungs sounded clear but recommended a course of antibiotics as a precaution against whooping cough due to my exposure. Although those antibiotics provided some relief for about a week, the cough eventually returned. In June, I sought help at urgent care, where the physician prescribed me a Wixela inhaler to be used twice daily over the course of a month. I am still using this inhaler. The doctor confirmed that my lungs appeared clear and suggested that I was experiencing a post-infectious cough along with reactive airway disease. Now, with only five days left of my inhaler treatment, I don’t feel I’ve made significant progress with my cough. It hasn’t been debilitating; more of a bothersome interruption. Typically, I’ll have a single strong cough and then be fine for a few minutes before needing to cough again. Aside from that, I don’t feel ill and can manage my regular activities without issue. I had asthma as a child, but I haven’t experienced any significant problems until now. I intend to revisit my PCP and ask for a referral to a pulmonologist, but I’m eager to hear if anyone here has insights into what might be causing my persistent cough?
