Concerns About My Purple Feet and Blister: What Could Be Wrong?
P I : (15M) (6 feet, 196 lbs) I reside in Argentina, specifically in a location where the weather generally hovers around 30°C. Recently, while engaging in some physical activity, I discovered a sizable blister on one of my feet. Initially, I didn’t think it was a significant issue until I and a family member observed that my foot had developed a worrying purplish hue. This prompted us to purchase hydrogen peroxide and an antifungal ointment for treatment. It's important to mention that a few months back, I dealt with a fungal condition in the same area where the blister appeared. As I pen this note, I’ve carefully drained the blister using a pin and applied the antifungal cream. Although my feet appeared to improve momentarily, they have reverted to that concerning purple color once again.

It sounds like you’re experiencing some concerning symptoms with your foot that require attention. The purple hue along with the blister could indicate a few issues, such as reduced blood flow, infection, or lingering effects from your previous fungal condition.
Explanation:
When a blister develops, especially from friction or pressure, it can sometimes become infected or cause changes in circulation, resulting in a purplish discoloration. This might be exacerbated given your history of a fungal issue in the same area. The fact that you drained the blister and applied an antifungal ointment is good initial care, but since the discoloration has returned, it suggests that there may be something more significant going on.
Next Steps:
-
Keep the Blister Clean and Covered: Ensure that the area is clean and protected with a sterile bandage to prevent further irritation and possible infection. Change the dressing regularly.
-
Monitor Symptoms: Watch for any changes. If you notice increased redness, swelling, warmth, or if you begin to develop a fever, these may indicate an infection which would require more urgent attention.
-
Elevate Your Foot: Try to keep your foot elevated to promote better blood flow, especially if you have been on it a lot during physical activities.
-
Limit Physical Activity: Avoid strenuous activities that stress your foot until it heals fully, as continued pressure may worsen the condition.
-
Hydration and Nutrition: Ensure you’re well-hydrated and eating a balanced diet to support your body’s healing process.
-
Consider Over-the-Counter Pain Relief: If you're experiencing pain from the blister or discomfort from the discoloration, medications like acetaminophen or ibuprofen can help provide relief.
If the purple discoloration persists or worsens despite these measures, or if you experience severe pain, I recommend seeking professional medical evaluation to rule out any significant underlying issues. Always prioritize your health and don’t hesitate to pursue further help when in doubt.

Elevated Bilirubin Levels with Right Side Abdominal Discomfort - Looking for Insights
I am a 33-year-old Caucasian male, standing 5 feet 11 inches tall and weighing 185 pounds. My daily medication consists of 20 mg of Adderall, and I engage in moderate to heavy drinking, typically having around 15 beers weekly (each at 6.5% alcohol content). Additionally, I use nicotine through vaping (specifically Juul) and utilize Zyn pouches. During a recent physical examination, my blood test results indicated a bilirubin level of 2.6. I have also been experiencing discomfort in my upper right abdomen, just beneath the rib cage. While my physician does not appear to be alarmed by these findings, the combination of the elevated bilirubin and my abdominal pain has raised some concerns for me. I would greatly appreciate any advice regarding this matter. Below are my complete blood test results for your reference: - Sodium: 136 - Potassium: 4.3 - Chloride: 99 - Carbon Dioxide: 29 - Calcium: 9.8 - Total Protein: 7.3 - Albumin: 4.8 - Globulin: 2.5 - Albumin/Globulin Ratio: 1.9 - Total Bilirubin: 2.6 - Alkaline Phosphatase: 41 - AST: 17 - ALT: 19
Persistent Discomfort Under the Jaw After a Neck Strain [39M]
In October, I sustained an injury when I excessively tensed my jaw and neck for an extended period. This resulted in considerable tightness beneath my chin on the left side, lasting for approximately one to two months. It reached a point where lifting my head caused notable pain and an awful pulling sensation. While the tightness has gradually subsided, I am left with a peculiar sensation as if the muscle in that area is continuously locked in tension or spasming. It's not exactly painful, but the discomfort is nearly constant, as if the muscle is still reactive and intermittently tightening on its own. Activities that require exertion, like straining during bowel movements, seem to exacerbate this issue and significantly elevate the sensation. Specifically, the discomfort persists on the left side of my neck right beneath the jaw. Despite it being four months since the incident, the issue lingers. I underwent an ultrasound in the affected area, but the results were normal. Although it doesn't appear to pose any serious problems, the ongoing sensation is quite frustrating and leads to daily discomfort. I am curious if anyone has insights into what this condition might be and whether it might resolve naturally over time?
Unexplained Health Issues – Seeking Insights
I’m a 24-year-old woman who has experienced a variety of unusual and progressively severe health symptoms over the past three years. My troubles began shortly after having my Nexplanon removed three years ago. Following the procedure, I suffered three episodes of intense pain accompanied by severe vomiting, which may have been linked to ovarian cysts, although the doctors' opinions differed after examining my scans. The vomiting ceased once I resumed taking birth control. However, shortly after, I began to experience debilitating abdominal pain and diarrhea. Initially, I was diagnosed with acid reflux; however, after taking famotidine and seeing some improvement, doctors considered the possibility of IBS since I developed sensitivities to dairy and gluten. I eliminated these foods and adopted a low FODMAP diet. Despite these changes, I continued to experience sporadic abdominal pain flares that didn’t correlate with specific foods. About five months ago, I encountered severe constipation that would last between ten to fourteen days, despite drinking plenty of water, exercising regularly, and using laxatives like MiraLAX and Dulcolax. The only remedy that provided relief was magnesium citrate. Interestingly, this extreme constipation occurred alongside my menstrual cycle two out of three times. More recently, about two months ago, I started suffering from persistent headaches that last all day. These headaches are focused in my temples and I’ve become increasingly sensitive to light. I’ve also been struggling with significant brain fog and difficulty maintaining focus. Blood tests have indicated that I am anemic, and I’ve also noticed blood in my stool. My family has a history of conditions including colitis, Crohn's disease, colon cancer, endometriosis, and ovarian cysts, which adds to my concern. However, my symptoms do not align perfectly with any specific diagnosis, leaving me feeling perplexed. For context, I am 5'2" tall, weigh 130 lbs, and I am currently managing my symptoms with psyllium husk, MiraLAX, magnesium citrate, an iron supplement (which I began taking four weeks ago), and vitamin D.
Challenges with Blood Clots and Vein Damage in My Arm
Hello everyone,I'm reaching out for assistance regarding a troubling health issue I've been experiencing. Back in early November, I underwent a procedure that involved placing an IV, which unfortunately has led to complications with my veins. Despite continually expressing concerns to my doctors post-surgery, it wasn't until after four weeks that I found myself in the emergency room. There, I discovered that over half of the veins had developed superficial clots. To manage the situation, I was prescribed Xarelto for 45 days, and I did notice some improvement. However, as soon as I finished the medication, the pain and swelling returned. Upon my follow-up visit, my doctor informed me that the clots persist in the superficial veins and have formed scar tissue. I can feel small lumps beneath my skin, and my doctor has since recommended an additional 90 days of treatment, increasing my dosage. He has switched my medication to Eliquis and advised me to wear a compression sleeve, despite the presence of clots in my hand as well. The condition of the veins in my hand remains unchanged; they have not improved and still appear dented. I recently engaged in some shoveling, which exacerbated the pain, now radiating to my upper arm. An ultrasound confirmed that there is no deep vein thrombosis (DVT), but I suspect there may be significant damage to my veins and their valves. My doctor has mentioned that repairs cannot be performed on superficial veins, which leaves me feeling quite frustrated. Living with this condition has become increasingly difficult, especially since the arm that had bicep tendon surgery is healing much better than this one! For some background, I am a 44-year-old woman, 5'5" tall, weighing 125 pounds, and I have been experiencing these symptoms for the past four months, residing in Boston. Moreover, I suspect I may be anemic due to the blood thinners I'm currently taking. My existing medications include 150 mg of Wellbutrin XL, 20 mg of Focalin, 15 mg of Benicar, and I'm now on 5 mg of Eliquis twice daily.
Persistent Coughing
Gender: Male Age: 16 Height: 188 cm Weight: 80 kg Medication: Cough syrup and various other pills. For the last three weeks, I've been plagued by a continual cough that just won't let up. In the initial week, I felt genuinely unwell, which likely contributed to the coughing. However, during the second week, I was feeling perfectly fine, yet the cough persisted. Now, entering the third week, I am no longer unwell; I do occasionally experience a runny nose, which seems to happen frequently. The cough itself is anything but dry; it’s accompanied by a thick green phlegm that leaves a nasty taste in my mouth. Despite trying numerous medications from the pharmacy, nothing seems effective, and I can't shake the feeling that my body is building up a tolerance to these treatments. Additionally, I’ve been dealing with an itchy sensation in my throat. To give some context, prior to this year, I was rarely ill—only getting sick about once a year, and it would typically last only a couple of days. However, this year has been a continuous struggle with illness.
