Understanding Patchy Discoloration After Sunburns
I’m a 27-year-old female who has been diagnosed with PCOS and struggles with a vitamin D shortfall. In hindsight, I discovered an occurrence while reviewing some older pictures from a few years back. I’ve noticed that after experiencing sunburns, I occasionally develop these unusual white patches on my skin. It’s quite puzzling since this has only surfaced a handful of times. I typically make it a point to avoid sunburn, so I'm not often in this situation, but it’s interesting to observe that not many others seem to have similar reactions to sunlight exposure. On the day I get sunburned, my skin typically presents a standard pink to red hue. However, when I wake up the next day, I find the color has transformed to this patchy appearance. I’m left wondering if this phenomenon is a typical aspect of skin healing or could it be related to the sunscreen products I apply?

The appearance of patchy discoloration on your skin after sunburn could be due to several factors, including the healing process of the skin, changes in pigmentation, or a reaction to sunscreen products. It's understandable to feel puzzled by these occurrences, especially since you've been proactive in protecting your skin from sunburn.
Explanation
When your skin gets sunburned, the body's healing response can lead to temporary changes in pigmentation. As the skin heals, some areas can appear lighter (hypopigmented) while others return to their normal color. This is more pronounced in individuals with lighter skin types and can also be influenced by factors such as previous skin conditions, hormonal imbalances related to PCOS, or even vitamin D deficiencies.
In terms of sunscreen, some ingredients can cause skin reactions, particularly in sensitive individuals, leading to unusual discoloration. If you consistently notice the patches coinciding with specific products, it may be worthwhile to investigate further.
Next Steps
-
Observe Patterns: Keep a diary noting when the discoloration occurs. Record any specific products you used and your sun exposure level to identify potential triggers.
-
Switch Sunscreens: Consider testing mineral-based sunscreens, as they often have fewer irritants and are less likely to cause reactions compared to chemical sunscreens.
-
Hydrate and Moisturize: Ensure your skin is well-hydrated with gentle, fragrance-free moisturizers, especially after sun exposure. This can support the healing process.
-
Protect Your Skin: Continue to avoid sunburn by using broad-spectrum SPF of 30 or higher, reapplying every two hours when outdoors, and wearing protective clothing.
-
Consultation (if needed): If the patches persist or worsen, a dermatologist can provide tailored advice and assess the discoloration for any underlying conditions.
Please keep monitoring your skin, and remember that taking proactive steps can help in preventing further occurrences while keeping your skin healthy!

Is a Burning Sensation from Mouthwash Common?
I've recently been using a mint-flavored mouthwash, specifically Crest's teeth whitening formula. However, it caused significant discomfort, stinging my lips and tongue to the point where I felt compelled to switch to Therabreath. Additionally, I had come across information suggesting that teeth whitening mouthwashes might harm your enamel. Therabreath also contains fluoride and mint, and while it still causes some burning, it's noticeably more tolerable than the previous brand. For a long time, I assumed this burning sensation was simply a normal part of using mouthwash, as I have experienced similar discomfort during dental visits throughout my life. To manage the sting from Therabreath, I've found that spitting it out before the pain becomes too intense has been a helpful strategy since it's not quite as severe. At this point, I am uncertain if my reaction is specific to mint or another ingredient present in the mouthwash. I have always disliked using mouthwash due to the discomfort it brings, but Therabreath is just tolerable enough that I keep using it. I'm turning to Reddit for advice first, as I would prefer not to visit my doctor only to be told that this sensation is typical and thus wasting her time. Being autistic, I sometimes find certain sensory experiences overwhelming, and it’s possible that I could just be particularly sensitive in this case.
What Could Be Causing These Symptoms?
I’m a 17-year-old female, standing 5 feet 9 inches tall and weighing 238 pounds. I’m not on any medications, have never smoked, and aside from some broken bones in the past, I don't have any significant health problems. Lately, for the last five days, I’ve been experiencing some unusual urinary symptoms. Each morning, when I go to the restroom, I feel a burning sensation during urination, and it has a strange odor reminiscent of cooked shrimp—definitely odd, right? Furthermore, my urine appears cloudy during this time. However, after I get through that first morning urination, I feel much better; the rest of the day my urine is almost completely clear, free of odor, and pain doesn't accompany it. I assure you, I still have the urge and the need to go frequently—I’m not just feeling the need without actually going. This is entirely new to me, as I’ve never experienced a urinary tract infection before or anything remotely similar. Additionally, I’ve never been sexually active, although I do own a rabbit vibrator that I meticulously clean after each use. Yesterday, I saw a doctor who had me provide a urine sample for testing. Fortunately, the results came back normal. They offered me antibiotics, although they suggested they might not be necessary. I chose to decline the antibiotics since the discomfort isn’t unbearable, but it does have me worried. The doctor plans to send the sample to a lab for further analysis to check for bacterial growth. I’m reaching out to see if anyone might have insights on what could be going on with me. I’d greatly appreciate any advice, reassurance, or explanations of what I might be dealing with. Please feel free to ask me any additional questions; I just want some clarity and support during this anxious time!
What Causes My Sudden Sleep Episodes?
At 18 years old, I find myself unexpectedly dozing off during the day. This occurs at random moments whenever I am seated, even while I am engaged in tasks. These episodes typically last about 5 to 10 minutes, during which I struggle to keep my eyes open. I eventually come to, with little memory of what transpired during that short time. My friends often mention that I fell asleep, yet I am still aware of my surroundings, albeit unable to concentrate. I also ensure to get around 9 to 10 hours of sleep each night, so I doubt that lack of rest is the problem.
Understanding My Lab Results: No UTI Detected – What's Next?
I’m following up regarding my previous post about my frequent urination issue while taking Prozac. On Monday, I visited my physician, and the preliminary results indicated a urinary tract infection (UTI). However, I received the official lab results today, which show no signs of a UTI. Interestingly, since being prescribed Macrobid, I've noticed that my urination frequency has actually increased. I reached out to my primary care doctor, endocrinologist, and psychiatrist, and I’m currently awaiting their responses. Given that my latest test results are negative, I’m starting to suspect that the Prozac may be the culprit behind this frequent urge to urinate. I’m trying to determine whether I should head to the emergency room or urgent care, which is quite a source of stress for me. The bright side is that I haven’t noticed any blood in my urine, which I hope indicates that things aren’t too serious. However, needing to use the restroom every 20 to 40 minutes is quite disruptive, and I’m at a loss regarding the best course of action! Below, I’m sharing my lab findings for reference. Thank you for your help! ### Healthcare Provider Comment "Hi, no signs of a UTI" ### Test Results - **Specific Gravity:** 1.028 (Normal) - **pH:** 7.0 (Normal) - **Urine Color:** Yellow (Unknown) - **Appearance:** Clear (Unknown) - **WBC Esterase:** 1+ (Out of Range) - **Crystals:** - Crystal Type: Mucus Threads (Unknown) - Bacteria: (Few, Unknown) - Yeast: NP (Unknown) - Trichomonas: NP (Unknown) - **Urinalysis Reflex:** NP (Unknown) - **Epithelial Cells (Non-renal):** 0-10 (Unknown, 0-10/hpf) - **Epithelial Cells (Renal):** NP (Unknown) - **Casts:** None Seen (Unknown) - **Urine Culture, Routine Result:** NP (Unknown) Overall, I am still trying to figure out what might be causing this irritating situation.
Could This Be a Blood Blister?
I'm a 32-year-old male, standing 180 cm tall and weighing 73 kg. Recently, I've been questioning whether I've developed a blood blister on my toe following my time playing padel, and I would greatly value some guidance on the matter. Due to my extensive history with racket sports, my feet are generally quite calloused. Initially, this particular area on my toe was concealed beneath a layer of callus and felt merely bruised and sensitive. I attributed this discomfort to the hard skin pressing against the softer tissue underneath. As I began to use a pumice stone to exfoliate some of the dead skin, I discovered a dark patch underneath. The area has become increasingly painful to put weight on, and the entire top of my toe experiences soreness and tenderness. After taking a brief hiatus from playing, the discomfort lessened significantly, but I returned to the court yesterday, and now I'm experiencing irritation and soreness once more. Could this condition be indicative of a blood blister beneath the callus? Should I refrain from any activity to allow for healing, or is there a recommended approach to managing this, such as utilizing padding, draining, or further removing callus layers?
