Should I Be Worried About This Bruise Behind My Knee?
I’m not a smoker and I’m not on any medications. A bruise appeared on the back of my knee on the 8th; it started as a small red dot and has since changed to a yellowish hue with some purple spots. I’m not sure how it happened, but it’s possible I bumped my calf while exercising. I began a workout routine about a month ago, but since noticing this bruise, I've experienced some discomfort relating to nerve issues in my hip, back, and right leg. It could be a pinched nerve or perhaps sciatica. I have refrained from exercising since I saw the bruise. Currently, I am feeling pain in my leg, but it’s difficult to determine whether it stems from the bruise or the longstanding nerve issues, which have been bothering me for a few years, albeit not typically this intensely. The sensations vary from sharp tingling in different areas of my leg and foot to mild cramps in the calf or thigh area, accompanied by a feeling of tightness that fluctuates. It does not hurt to walk, and while the discomfort is consistently mild, it is still present. There’s no swelling or redness around the bruise. The color of the bruise is a bit more vivid when seen in person. Should I consult a doctor about this? Is it merely a common bruise, or is there a risk it might be something more serious, like a blood clot?

It's understandable to be concerned about a bruise, especially when accompanied by discomfort and other symptoms. Based on your description, the bruise likely reflects a common injury, especially given your recent increased activity. However, the ongoing nerve sensations and discomfort do merit careful consideration.
Explanation:
Bruises can develop from minor injuries, and their color changes over time as they heal. Your description of the bruise changing from a red dot to yellowish with purple spots is typical of the healing process. Although you mentioned possible pinched nerve or sciatica symptoms, it's important to remember that discomfort due to nerve issues can sometimes be misleading and might not be directly related to the bruise.
Here are some signs that warrant further investigation:
- Severe pain that worsens rather than improves.
- Any sudden swelling, increased warmth, or color changes in the limb.
- Symptoms such as weakness or loss of sensation in the leg.
Next Steps:
-
Monitor the Bruise: Keep an eye on the bruise for any significant changes such as increased size, pain, or any new symptoms. If it doesn't improve over the next week or if other concerning symptoms arise, seek medical advice.
-
Manage Discomfort: Since you're not experiencing significant pain when walking, it's okay to gently move and stretch. Light activities can help maintain mobility without aggravating the bruise.
-
Ice and Rest: Consider applying ice to the bruise for 15-20 minutes several times a day for the first couple of days to reduce any potential inflammation (if necessary). Resting the leg while avoiding strenuous activities can help alleviate discomfort.
-
Evaluate Nerve Symptoms: Pay attention to the nerve sensations you described. If they persist or worsen, or if you experience any new symptoms like weakness, schedule time to discuss these with a healthcare provider sooner rather than later.
If you feel uncertain or if symptoms escalate, don't hesitate to consult a healthcare professional for a thorough evaluation; it's always better to err on the side of caution. I'm here if you have further questions or need help navigating your symptoms!

Chronic Foot Pain: Seeking Insights on Possible Causes
I'm reaching out to gather thoughts on a perplexing issue I'm facing. Since my first pregnancy back in 2020, I've been dealing with intense foot pain that appears unpredictably. It all started when I was about seven months along while working long shifts in a busy kitchen, four days a week, for eight hours each day. At the time, I dismissed the discomfort as something typical for pregnancy, but it fortunately subsided about six months after giving birth to my first child. Fast forward to late 2024, when I became pregnant with my second child. By now, I had transitioned to being a stay-at-home mother, with none of the rigorous demands of my previous job. However, around three months into this new pregnancy, the foot pain reemerged and has persisted ever since. My youngest is turning two this month, which helps frame this timeline. The pain has oscillated between being severe and manageable, but the previous six months have marked a significant decline into debilitating territory. When I am at rest, I feel sharp pains in my metatarsals that radiate up to my knees. To alleviate some discomfort, I’ve been altering my walking style to shift weight more onto my heels instead of the balls of my feet. However, this adjustment has introduced a new level of discomfort in my heels. Ironically, the only relief I find is while walking. Nonetheless, excessive walking—even something as simple as taking my oldest to school for a brief ten-minute journey—leaves me nearly immobilized the following day. Currently, I’m on a regimen of 50 mg of APO-Diclofenac DR, taken twice daily, yet I’ve found no relief. Previously, I also tried 500 mg of naproxen twice a day without any positive outcomes. I've experimented with various footwear, but none have alleviated the pain. My primary care physician has arranged for bilateral x-rays and blood tests to check for conditions like gout and markers for osteoarthritis and rheumatoid arthritis, among other things. So far, all tests have returned normal. There have been occasions where I’ve had to keep my oldest child at home from school simply because I’m unable to walk even a short distance, such as the fifty steps from my bedroom to the kitchen. Standing causes distress, and even elevating my feet while resting feels unbearable. Additionally, any gentle touch to my feet triggers intense pain that shoots up my shins. The only feedback I’ve received from my doctor so far is that it likely stems from inflammation, along with a recommendation to expedite weight loss. I had a chiropractor assess my condition, and they noted that I am hypermobile, but I’m unsure how significant that could be to my situation. If you have any questions for clarification, I’d be more than willing to respond. I’m enduring considerable pain and would greatly appreciate any suggestions on possible avenues for finding relief.
Managing Pain with Lidocaine Patches and Heating Pads
Hello everyone! I need to share something quite personal: I have been diagnosed with cancer. I realize that’s a heavy way to start, but it’s important context. Currently, I am using a lidocaine patch as a method for pain relief. However, I’ve found that my heating pad provides more comfort than the patch does. Is it advisable to remove the patch and switch to the heating pad instead? Should I clean my back prior to using the pad, even though it’s not a day I usually shower? Also, once I take off the patch, how long should I wait before applying the heating pad again? I appreciate any advice you have! For reference, I’m approximately 5 feet 5 inches tall and weigh around 250 pounds.
Discomfort Under My Big Toe – Seeking Diagnosis
I’m a 22-year-old male. About a week ago, I noticed a minor ache in my big toe, which didn’t bother me too much at the time, so I decided to brush it off. However, by yesterday, the discomfort had intensified significantly. I also observed some swelling and a bit of discoloration, but I'm unsure whether this issue stems from a corn, a blister, or something else entirely. I would greatly appreciate any assistance in identifying what might be going on.
Sudden Stabbing Throat Pain
As a 19-year-old female, I find myself dealing with a sudden, intense pain localized on the right side of my throat, adjacent to my windpipe and beneath my chin. These episodes are unpredictable; they strike without warning, persist for just a fleeting moment, and then vanish completely. This situation is genuinely concerning for me. I'm at a loss for how to alleviate this discomfort. Has anyone encountered a similar issue or have any insight into what could be causing this?
Understanding Limited Finger Mobility and Associated Discomfort
I’ve noticed that my right hand struggles with having individual finger movement. To illustrate this challenge, I recently recorded a brief video showcasing my hand's limitations. Additionally, I’ve been dealing with persistent neck and shoulder pain for several years now. Despite consulting multiple healthcare professionals, I’ve yet to receive any conclusive answers regarding my condition. I’m currently attending physical therapy, but even my therapist seems puzzled by the situation. An MRI of my neck returned results indicating only mild issues, and the same goes for my shoulder, with nothing alarming detected. I would be immensely grateful for any insights or suggestions, particularly since the discomfort has forced me to halt my weightlifting training.
