Changes in Abdominal Skin Color
Age: 29 / Height: 5 feet 4 inches / Weight: ranges from 115 to 130 pounds / Diagnosed with Hashimoto's disease and a history of Lyme disease. For approximately four years, I've noticed a change in the color of my abdomen, which appears to intensify when exposed to sunlight. Over time, this discoloration has increased in size. There’s no associated itching, and the affected area feels similar to the surrounding skin. Additionally, I experience persistent issues with chronic pain and fatigue, although these symptoms may not be connected to the skin condition. Could anyone offer insight into what might be happening? Would it be advisable to consult a dermatologist regarding this issue?

It sounds like you're experiencing a significant change in your abdominal skin color that has persisted for several years and worsens with sun exposure. Given your history of Hashimoto's disease and Lyme disease, it's understandable to be concerned about these changes.
Main Points
- Potential Causes: Skin discoloration can result from several factors, including sun exposure, hormonal changes, inflammation, or other medical conditions affecting pigmentation.
- Importance of Monitoring: Since the discoloration has increased in size and you have a chronic health history, it’s wise to monitor it closely.
Explanation
Sun exposure can lead to hyperpigmentation, which may present as brown or darker areas on the skin. Sometimes, autoimmune conditions like Hashimoto's can also affect skin health. Other possible causes include changes in hormones, medications, or underlying skin conditions, but the absence of itching or other symptoms makes more serious issues less likely.
Chronic pain and fatigue, while seemingly separate from the skin issue, warrant attention as they may indicate systemic concerns that should not be overlooked.
Next Steps
- Track Changes: Keep a diary of the color changes in your abdominal skin—note any changes in size, color, or texture over the next few weeks. This will help provide important information for any healthcare provider.
- Sun Protection: Use a broad-spectrum sunscreen daily to protect your skin from further discoloration due to sun exposure, particularly on the affected area.
- Consult a Dermatologist: It is advisable to see a dermatologist, especially since you have a history of other health issues. They can perform a detailed assessment, potentially including a skin biopsy if necessary, and offer targeted treatment options.
Your health concerns are valid, and seeking a professional's advice can help clarify the situation and provide you with the reassurance you need. Let me know if you have further questions or need more guidance!

Navigating My Health Struggles
I've shared snippets of my health issues in the past, but I’m really at a breaking point. The continuous pain I experience makes me contemplate escaping my reality, not in a dramatic way—just out of sheer exhaustion. I’m only seventeen, weigh 240 pounds, and stand 5'3". Illness has plagued me for as long as I can remember. Initially, my stomach troubles and joint discomfort were dismissed as mere growing pains and childhood anxiety. However, at thirteen, I developed Postural Orthostatic Tachycardia Syndrome (POTS) following a severe bout of COVID I contracted during a trip to Italy. Since then, my health has deteriorated significantly. I endure persistent stomach aches that swing between constipation and diarrhea, sometimes accompanied by blood. I also have random skin reactions, manifesting as fiery rashes on my face, chest, and hands whenever I'm exposed to air or sunlight. The pain in my joints is relentless, with my body occasionally experiencing subluxations, where joints dislocate. To add to this, my left foot has been misaligned since birth, causing me to limp. Recently, I began coughing up mucus with blood—dark, rusty clots, along with vivid streaks. I suffer from frequent tachycardia, episodes of dizziness, and fluctuations in my blood pressure. Muscle twitches, spasms, and inexplicable numbness and tingling in my lower body are now my daily companions. The pain seems unending. Doctors often suggest my symptoms are purely psychiatric, but I can't help but wonder what mental health condition would cause blood in my cough or skin rashes. I feel frightened, in constant discomfort, and incredibly isolated. Although they’ve recommended a wheelchair for mobility, the prevailing sentiment seems to suggest the root of my suffering lies solely in my mind, which leaves me feeling dismissed and unheard.
Concerns Regarding Brain MRI and Eye Flashes
Hello everyone, I'm new to this community! I’m a 28-year-old female and lately, I’ve been dealing with peculiar flashes in my vision that consistently appear in the same location—they never seem to fade away. Additionally, I experience about two severe headaches annually, which are intense but eventually subside; however, those visual disturbances persist, shifting in appearance from black to a black-and-white hue. My neurologist believes these symptoms are tied to migraines, but considering I only suffer from two headaches each year, I find it hard to comprehend. I have an MRI appointment coming up, and I’m feeling quite anxious about it. I’ve also decided against using contrast dye—not because I fear the injection itself, but due to alarming tales I’ve come across and the fact that it contains heavy metals. Is it truly essential to have the contrast? Can it reveal information that a non-contrast scan wouldn’t? I’d appreciate any insights or advice about the need for contrast in this situation. It’s worth noting that I specifically chose a facility that utilizes a T3 machine to avoid the contrast. Thank you for your help!
Concerns About Ongoing Symptoms
It all began last November when I first experienced symptoms including a mild fever, a sore throat, and a raspy voice. This illness returned the following month with the same low fever. Occasionally, I found the fever would reappear at random intervals, occurring consistently around the same time each month. After some medical evaluations, I was diagnosed with mononucleosis, alongside developing petechiae. In April, my initial symptoms began to fade, yet I noticed swollen lymph nodes in my neck. This leaves me wondering if these could merely be a lingering effect of the mono, or if they could indicate a more serious issue. I should mention that I am only 14 years old.
Popping Sound on the Outer Side of My Left Knee
I am a 45-year-old man. Back in 2016, I injured my knee, and ever since, I've experienced a distinct popping sound on the outer side of my left kneecap when I extend it outward. Alongside this, I'm grappling with a sensation of instability; at certain angles, it feels as if my knee shifts, causing excruciating pain until it eventually settles back to a normal state. Lately, I've become increasingly aware of how I move my knee, and I fear that the situation is deteriorating.
Persistent Oral Lump Inquiry
A 30-year-old woman shares her experience with a lump in her mouth that she first noticed in 2020. Although the lump hasn't disappeared completely, it has slightly decreased in size over the years. She has consulted with three ENT specialists who have either dismissed it as inconsequential or indicated they couldn't identify anything of concern. The lump does not cause any pain when touched, but she has observed an increase in its size during her current battle with strep throat, reminiscent of its initial growth back in 2020. Despite frequent visits to the dentist, she reports that none have addressed the lump during her appointments. She is contemplating whether it would be wise to seek a second opinion. Is it advisable to consult another healthcare professional regarding this issue? Thank you for your assistance.
