Post-Treatment Sediment in Urine Despite Negative Test Results

3/19/2025, 3:20:29 PMMale25-34

I am a 5'3" female with no current medication and no significant health issues aside from what has already been discussed. I was prescribed doxycycline for a skin issue known as perioral dermatitis, and I also took it as treatment for chlamydia. I consistently took the medication every day but at varying times. While I’ve observed that all my chlamydia symptoms have disappeared and my skin has improved, I’m still noticing white sediment or floating particles in my urine following the treatment. I recently conducted a rapid test, which came back negative. What could be causing this?

It’s great to hear that your symptoms of chlamydia have resolved and that your skin condition is improving. However, noticing white sediment or floating particles in your urine can understandably be concerning. Let's break down the possibilities you might be encountering.

Possible Causes of White Sediment in Urine:

  1. Crystals: Sometimes, urine can contain crystallized substances, which might appear as sediment. This can happen if you're dehydrated, eating certain foods, or have an altered pH in your urine.
  2. Mucus: Mucus from the urinary tract can give the appearance of floating particles. This is often harmless but can be exaggerated by certain dietary factors or mild infections.
  3. Infection or Inflammation: Although your rapid test for chlamydia was negative, other issues such as a urinary tract infection (UTI) or inflammation could cause sediment. Symptoms might not always be present, so it's something to keep in mind.
  4. Doxycycline: While it's less common, antibiotic use can sometimes alter mineral levels or the composition of urine, leading to sediment.

Next Steps:

  1. Stay Hydrated: Aim to drink plenty of water (about 8-10 glasses per day) to help dilute your urine and possibly reduce sediment.
  2. Monitor Symptoms: Keep an eye on your urine's appearance over the next week. Note any changes including color, smell, and any new symptoms like burning during urination or increased frequency.
  3. Diet Considerations: Pay attention to any recent dietary changes or food that might influence your urine's appearance (e.g., beets, asparagus).
  4. Consider Re-testing: If the sediment persists beyond a week or if you develop any new symptoms, it might be worthwhile to contact a healthcare professional for a re-evaluation and possibly a urinalysis.

While changes in urine can often be benign, monitoring the situation and staying hydrated are crucial. If you need further advice or support, don’t hesitate to reach out!

Seeking Clarity on My Wife's Tragic Accident

Hello, healthcare professionals. I am reaching out with a heavy heart, seeking clarity on the unfortunate incident that led to my wife's untimely demise. She was only 29 years old and worked as a doctor, and she lost her life in a scooter accident while on her way to work. **Accident Overview:** According to the report provided by the police, my wife was struck by a speeding vehicle that aggressively cut her off, causing impact at the left rear section of her scooter. It's important to note that this occurred in India, where vehicles drive on the left side of the road. Even though she had a helmet on, she sustained severe head injuries and tragically succumbed at the scene. While I understand that no amount of information can bring her back, I am desperate to know whether her passing involved suffering or if it was a quick transition. Here’s a summary of the injuries noted in her post-mortem report: |Injury Location|Description| |:-|:-| |**Head and Face**|Blood was present in her ear, nose, and mouth. There was a reddish bruise measuring 3x3x1cm on the right side of her scalp. Underneath this bruise, a depressed fracture was visible in the right temporal bone, and her pupils were dilated.| |**Brain and Meninges**|The dura mater had a tear in the right temporal area. There was a contusion in the right temporal lobe accompanied by slight subarachnoid bleeding. Additionally, there was minor subarachnoid bleeding observed in the left parietal lobe.| |**Neck and Throat**|Both the larynx and trachea contained aspirated blood, which was also noted in the trachea and bronchial tubes.| |**Chest**|Fractures were found in the right 3rd and 4th ribs along the mid-clavicular line.| |**Skin Injuries**|On her right shoulder, there was a 2x2cm reddish abrasion. A 6x5cm reddish abrasion was found on her right elbow, a 1x1cm region on her right knuckles, a 4x2cm abrasion on her right knee, and a 5x2cm abrasion on her left knee.| |**Internal Injuries**|Blood was present in the mouth, pharynx, and esophagus, while the stomach contained 10ml of blood-stained fluids.| I am grappling with the question of whether she experienced pain during her final moments. Did she have any awareness of her surroundings, or did her life end rapidly? I seek frank responses regarding her experience before her passing. Please, no sugarcoating. Rest assured, I am prepared for any information, as I am currently undergoing both psychiatric and psychological support. I simply wish to know what truly transpired. If there’s anything specific that you need from me to assist in your appraisals, please feel free to reach out in the comments. I just want to uncover the truth.

Experiencing Medical Adhesive for the First Time

I apologize for the awkwardness of this message, as I’m typing with my non-dominant hand. I'm a young woman, and an incident occurred while I was drinking. To keep it brief, I managed to accidentally slice the tip of my thumb off about two hours ago. Thankfully, it wasn’t an extensive injury, but enough to cause bleeding that lasted for roughly 30 minutes, even with pressure applied and my hand elevated. (For context, the cut extends a few millimeters deep, penetrating beyond just the surface layer of skin.) Following the accident, I visited the hospital where they applied medical glue, wrapped it up, and discharged me. As I was leaving, I began experiencing some pain, which persists. Upon returning home, I noticed some blood on the gauze covering the injury, which appeared roughly an hour after I got back. Is this typical? The hospital did not provide any pain relief, which I’m not overly concerned about since it is only my finger, but my tendency to be a bit of a hypochondriac is making me anxious. This is my first experience with such an injury. What’s the recommended method for cleaning it once I change the dressing? Thanks in advance!

Seeking Guidance on Long-Term Shoulder Muscle Loss After Dislocation

I am a 25-year-old male, and five years ago, I experienced a dislocation of my left shoulder. While the joint has healed well and I have regained a good range of motion, the muscle in my shoulder has not recovered. There is a noticeable difference in muscle mass when compared to my right shoulder. Additionally, I have lost sensation in the area where the muscle has atrophied. When I touch that spot, I feel almost nothing at all. I recall being informed that sensation might return within six months to two years, but unfortunately, that hasn’t happened. In the gym, I've also realized that my left shoulder functions improperly during workouts. While performing chest and shoulder exercises, it seems as though my triceps compensate excessively, rather than the shoulder muscle engaging as it should. This leads to a very frustrating and unbalanced training experience. At this juncture, I’m concerned that the issue may stem from lasting nerve damage caused by the dislocation. I’m curious whether it’s still feasible to rebuild the muscle or regain sensation after such a lengthy period, or if this condition is likely permanent. Have others found themselves in similar situations years later, and did they manage to make any progress or uncover the root cause of their issues? I’m not seeking a diagnosis; I simply wish to understand if the muscle damage is irreversible or if there remains a possible pathway to recovery. What steps should I consider taking next? I would greatly appreciate any advice or insights regarding my situation. Thank you!

Appropriate Use of Athletic Tape for Swimmers

To provide some background, I’m a 17-year-old female and currently competing in high school swimming while dealing with a knee injury. Essentially, my knee joint is unstable, and it will take several months for recovery. Both knees are affected, and I experience a constant pain level of around 7 out of 10. I've been advised to undergo physical therapy and to utilize athletic tape while swimming during my recovery, along with having to rely on knee braces for long-term support. However, the issue I face is that the tape tends to come off during school hours, and I can’t use my knee brace while I’m in the water. I’m looking for suggestions on how to better secure the tape or if I should consider wrapping it entirely around my knee. Any advice would be greatly appreciated!

Considering Surgery for a Ganglion Cyst: Is It Justified?

At 32 years old, I've been dealing with a ganglion cyst on my right wrist for nearly nine years, and it shows no signs of disappearing. After consulting with a hand surgeon, I was informed that the cyst is positioned quite deeply. My choices are either to tolerate it or undergo surgical excision. I'm grappling with the decision of whether the surgery is worthwhile. On one side, this condition disrupts my daily life; it leaves me with a sense of wrist weakness. I frequently experience a persistent ache that intensifies after long hours at my desk, while driving, or engaging in exercises such as planks and push-ups. I also feel discomfort from simply holding my phone for an extended period. However, I weigh these inconveniences against the potential complications of surgery, the recovery period, and the possibility of needing time off work. Moreover, there’s the risk of the cyst returning afterward, which adds to my uncertainty. I would greatly appreciate any insights or personal experiences from those who have faced a similar dilemma.
