Is It Just Peroneal Tendonitis or Something More Serious?
As a recent 22-year-old college graduate, I've always identified as an athlete. However, during my final year at university, I let my fitness routine slip a bit, resulting in some unwanted weight gain. To change that, I began running around six weeks ago. Initially, everything was going quite well; I was completing runs of 2 to 4 miles, three to four times a week. My pace was improving, and I felt physically strong. However, I made a spontaneous decision to participate in a 10K event, which I surprisingly managed well. I didn’t experience much soreness afterward, but that relief was short-lived. The following morning, I woke up with a persistent, bruise-like discomfort on the outer area of my mid-foot. While resting eased the pain, stepping on it was extremely uncomfortable. Concerned, I visited a nearby urgent care where I underwent x-rays to eliminate the possibility of a stress fracture. Fortunately, the results showed no fracture, and the attending physician diagnosed me with a sprain, suggesting a period of rest. Unfortunately, and perhaps somewhat foolishly, I opted for only a week of rest before attempting to run again. I convinced myself I was ready since the pain had diminished enough to make walking tolerable. Testing my foot turned out to be a poor decision. That run occurred five days ago, and since then, I've found myself limping around awkwardly. The discomfort, which initially resided in the sole of my foot, has now extended beneath my ankle bone and above the mid-foot area. I’m still unable to bear my full weight on it; although I've noticed some slight improvements in mobility, the pain, while less severe than the original episode, makes me suspect that this injury could be more complicated than mere tendonitis. Is it normal for pain to escalate to this level? From previous encounters with tendinitis in my elbow due to baseball, I can say that this experience has been far more intense and troubling than anything I've faced before.

It sounds like you're experiencing significant discomfort in your foot after resuming running too soon following an injury, which may complicate your recovery. While tendonitis is a possibility, the symptoms you're describing can also suggest other issues, such as ligament strain or even early signs of other conditions.
Explanation: A sprain or tendonitis can lead to localized pain and discomfort, especially if the area isn’t given adequate time to heal. Running too soon after an injury can exacerbate inflammation and lead to further issues, like extending pain into areas of the foot that were previously unbothered. Given your active lifestyle and the recent change in your running regimen, it's essential to thoroughly assess and address your pain.
Next Steps:
-
Rest and Ice: Begin with complete rest from weight-bearing activities. Ice your foot for 15-20 minutes several times a day to help reduce swelling and pain.
-
Elevation: Keep your foot elevated as much as possible to minimize swelling. This can help reduce discomfort when you’re at rest.
-
Pain Management: Over-the-counter anti-inflammatory medications, such as ibuprofen, can help alleviate both pain and swelling. Be sure to follow the recommended dosage.
-
Gradual Mobility Work: Once the pain and swelling decrease, begin gentle range-of-motion exercises to gradually improve mobility without causing pain. Avoid any movements that increase discomfort.
-
Reassess Your Progress: Monitor your symptoms closely over the next week. If you notice persistent significant pain, swelling, or difficulty with mobility, re-evaluating your condition with a healthcare professional may be necessary to rule out more serious injuries.
-
Footwear Check: Make sure you are using appropriate footwear that offers support for your running style. Consider consulting a professional for a gait analysis if needed.
By following these steps, you can lay the groundwork for a safer return to physical activity while minimizing the risk of further injury. Stay mindful of your body's signals, and don’t hesitate to reach out if your situation changes or worsens. You’re not alone in navigating recovery, and prioritizing your health now can help ensure a successful return to running in the future.

Persistent Cough Following Cold – Seeking Insights
At 42 years old, I have no significant health concerns aside from a lack of regular exercise and not maintaining an ideal diet. About three months back, I experienced a common cold, and my recovery was typical. However, since that time, I've been plagued by a persistent urge to cough, which can be quite intense. There's a peculiar sensation near my diaphragm and heart that feels like a flutter, and at times, it feels as if my heart is momentarily skipping a beat during these episodes. This unsettling flutter began right after my cold, and it's a feeling that’s completely unfamiliar to me. During bouts of intense coughing, I occasionally bring up small amounts of clear mucus, but I don't experience any other symptoms. On average, I find myself coughing in short bursts about 10 to 20 times each day. Often, particularly when I’m sitting up in bed late in the evening, this fluttering sensation can feel relentless, leading to a cough approximately every 30 seconds—sometimes even more frequently—for an hour or two. I have consulted my primary care physician on two occasions, and pneumonia has been convincingly ruled out. I’ve experimented with a steroid treatment and took Claritin, along with trying virtually every over-the-counter cough remedy available, but nothing seems to provide any relief. What further steps should I consider taking to either eliminate potential issues or help find a remedy to this ongoing situation?
Cysts on Liver Detected in Chest CT: Should I Be Concerned?
I am a 34-year-old female who does not smoke or consume alcohol, and I don’t take any medications aside from vitamin D supplements. My weight is 145 pounds and I stand 5 feet 3 inches tall. Despite my healthy lifestyle, I find myself feeling anxious. Recently, I have been experiencing pain on the left side of my chest, accompanied by shortness of breath, excessive sweating, and discomfort in my back and joints. My diet has included more dairy products recently, and I am beginning to wonder if I might be allergic or if there could be a more serious underlying issue. Today, I had a sensation of post-nasal drip followed by a cough that produced dark, bloody mucus, which was alarming as I have never encountered anything like this before. Currently, I am at the emergency room, where a very understanding doctor reviewed my CT scan and confirmed that there were no signs of a pulmonary embolism or heart problems. He also stated that my blood tests appeared normal. However, he did mention the presence of some cysts on my liver. How concerned should I be about these findings? Is it advisable for me to discuss this further with my gastroenterologist?
Seeking Guidance on Complications Post Hip Replacement
I am a 59-year-old female who underwent a left total hip replacement using a Mako robotic approach in December 2024. Initially, post-operative discomfort subsided, but I have been experiencing persistent pain in the back of my left hip that has not improved. Throughout my follow-up appointments, I expressed my concerns to both the surgeon and the physician assistant, but they only suggested that I wait it out without providing further options. During my most recent visit in early May, I was informed that I might have bursitis; however, no specific treatment was recommended, and I was advised to get an MRI of my lower back. Following that, I reached out to my primary care physician for a referral for both back and hip MRIs, which were conducted at the end of June. The hip MRI revealed a defect in the posterior left pseudocapsule, with an organized collection of joint fluid extending along the back of the greater trochanter. The lumbar MRI indicated the presence of disc osteophyte complexes at the L4/5 and L5/S1 levels. I have a follow-up appointment with the orthopedic specialist next week, but I am feeling quite frustrated due to my previous experiences where my pain was not taken seriously, and the reluctance to pursue a hip MRI earlier. Although this doctor comes highly recommended in our medium-sized town, I am uncertain about my next steps and where to seek further assistance. Clearly, it’s essential to address these issues, and I would appreciate hearing from others regarding potential diagnostics or treatment options, as my confidence in the current diagnosis process has waned considerably.
