Struggling with Recurrent Cellulitis from Insulin Pump and CGM Usage
I’m a 25-year-old male who weighs 160 pounds, and my average blood glucose has been around 120 over the past three months. I’m currently utilizing the Dexcom G7 continuous glucose monitor (CGM) alongside the Omnipod 5 insulin pump, and I was recently prescribed doxycycline for treatment of an infection. Since April, I've experienced two episodes of cellulitis. The most recent infection is located on the upper part of my arm from my CGM, while the initial one occurred on my thigh linked to the insulin pump. I'm at a loss regarding what I might be doing incorrectly. I consistently clean the insertion sites; I use Dr. Squatch soap along with water during my showers and follow up by wiping the area with an alcohol swab. Just two days ago, I felt discomfort at the CGM location (which I removed three days prior due to inaccurate readings), and today the site appeared inflamed and red. Unfortunately, it has become infected, and I’m seeking treatment. I would greatly appreciate any advice on how to prevent such infections moving forward. During my visit to urgent care, the doctor mentioned the possibility of having staph bacteria present on my skin and recommended disinfection. This was new information to me!

It sounds like you're dealing with recurrent cellulitis, which must be really frustrating, especially since you’re managing diabetes with an insulin pump and CGM. Let's break down the situation and find effective strategies to help prevent these infections from occurring in the future.
Understanding the Situation
Recurrent cellulitis often stems from bacteria, including staphylococcus aureus, which can live on the skin. The fact that you've been using an insulin pump and CGM increases the likelihood of skin irritation and infection at the insertion sites, especially if bacteria enter through tiny openings.
Immediate Steps
-
Cleanliness at Insertion Sites:
- Continue using mild, antibacterial soap, but consider switching to a soap specifically formulated for sensitive skin and infection prevention if irritation persists. Make sure to rinse thoroughly and dry the area completely.
- After cleaning, use a new alcohol swab to sanitize the skin around the insertion site. Allow the skin to dry completely before inserting your CGM or pump.
-
Insertion Technique:
- When inserting the CGM or insulin pump, try to minimize the amount of pressure applied. Consider rotating insertion sites more frequently to different areas that are less prone to irritation.
-
Monitoring and Care:
- Keep a close watch on the sites. If you notice any redness, swelling, or discomfort, react promptly. Early recognition can prevent full-blown infections.
- Apply a topical antibiotic ointment (like bacitracin) to the insertion sites after you clean them, especially if you tend to experience irritation.
-
Avoid Tight Clothing:
- Wear loose-fitting clothes that do not rub against these sites to reduce irritation and the potential for bacteria to enter.
-
Consult on Prophylactic Measures:
- Discuss with your healthcare provider the option of using a preventive topical antibiotic treatment before and after insertion. Given your history, this might provide additional protection.
Search for Persistent Problems
- If cellulitis recurs despite these preventive measures, it may be beneficial to explore underlying issues like skin sensitivity or immune function, especially given your diabetes. Regular follow-ups with your healthcare team can help in finding tailored solutions.
Additional Support
- Make sure to regularly check your blood glucose levels, as poor glycemic control can contribute to slower healing and increased infection risk. Aim for stable blood glucose levels within recommended ranges.
Psychological Support
- Chronic conditions can be challenging to manage. Consider joining a support group for individuals with diabetes or chronic conditions to share experiences and coping strategies.
Please continue to monitor your symptoms closely and implement these changes. Let me know if you’d like more information on any aspect!

Concerns About Angular Cheilitis
I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.
Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.
Post-Gallbladder Surgery Concerns: Potential Infection Three Weeks Later?
Subject's Age: 35 Gender: Female Height: 5 feet 4 inches Weight: 160 pounds Ethnicity: Asian Duration of Symptoms: Last Three Weeks Geographic Location: United States Relevant Medical History: Almost three weeks ago, I underwent gallbladder removal surgery. In the last few days, I have observed a small amount of cloudy discharge emerging from my incision site. Recently, I noticed what appears to be pus leaking from the area. While there is no significant pain, I do feel a mild soreness when I touch or move the site. I have not experienced any fever or chills, and there’s no unpleasant odor coming from the wound. Should I continue to clean the area with soap and water, or is it advisable to seek medical attention at the emergency room for further evaluation?
Seeking Insight on Abnormal Neuroimaging Results
A 42-year-old female, standing 6 feet tall and weighing 194 pounds, has been grappling with cognitive challenges for over three years. She has a clinical history that includes a diagnosis of Bipolar II disorder coupled with generalized anxiety, which she manages effectively through a regimen of an antidepressant, a mood stabilizer, and medications for anxiety. Currently, she is under the care of her fifth neurologist in the Boston region. An FDG-PET scan revealed a significant decline in metabolic functions, showing a 30-40% reduction within the left parietal lobe and a 20% decrease in both mesial temporal lobes. As part of her evaluation, a lumbar puncture was performed to assess amyloid and tau protein levels, with results coming back negative. Although a radiologist recommended pursuing an amyloid PET scan to gain further insights, her neurologist has declined this option. Despite the neurologist's suggestion that her indications might fit into the Functional Neurological Disorder (FND) category, she remains unconvinced and believes there must be an identifiable underlying cause for her symptoms and the irregularities observed in her scans. She is seeking advice on the next steps to take in pursuing a clearer diagnosis or understanding of her condition.
Light Pink Discharge After Urination
Just yesterday, after using the restroom, I spotted a faint pink hue on the toilet paper. Initially, I thought it might indicate the start of my menstrual cycle, especially since I didn’t have my period last month during the last week of January. However, today I haven't noticed any blood, and I don't anticipate any appearing this week or even the next. Additionally, I observed small traces of blood in my urine during the week my period was supposed to arrive. While I do experience some hormonal symptoms, I’m uncertain about their meaning. Thankfully, I haven’t felt any burning sensations, but I find myself feeling confused and, to be honest, a bit anxious about the situation. I maintain an average weight, I’m not on any medications, and I do not smoke.
