Bladder distension sensation


Hello, two days ago I took three over-the-counter pills (Xing Lulu) due to chills and body aches.
The next day, I felt some improvement, but by the afternoon, I started to feel a swelling sensation in my bladder.
There doesn't seem to be any issues with urination; I don't have frequent urination, and it doesn't hurt to urinate, although there are a bit more bubbles than usual.
However, I still feel a swelling sensation in my bladder and lower abdomen.
Since I still have some chills and body aches, I took two more pills.
Today, the swelling sensation has not disappeared, and I'm worried that something might be wrong.
I kindly ask the doctor for clarification.
(The swelling sensation is more pronounced when sitting or lying down, but feels better when standing.)

Hello: There may be other issues at play, as inflammation can cause chills and body aches.
Some individuals may experience urinary symptoms with this type of cold medication (not everyone).
There should be no abnormalities in urination, as there is no frequency or pain associated with it, so there shouldn't be a major concern.
However, the chills may warrant attention, as a fever could develop.
It's important to maintain adequate hydration, and if a fever occurs, seek medical attention immediately.
New Lulu is an over-the-counter cold medication (is it still within its expiration date?).
If there is no improvement after using it for 1-2 days, medical consultation is advised.
(If you have taken this medication in the past without such issues, it is still best to consult a doctor.) Thank you for your inquiry.

More Info


Bladder distension can be a concerning symptom, and understanding its potential causes is essential for addressing any underlying issues. Based on your description, it seems that you are experiencing a sensation of bladder swelling or fullness, accompanied by some discomfort in the lower abdomen. While you have not noted any changes in urination frequency or pain during urination, the persistent feeling of distension warrants further exploration.


Possible Causes of Bladder Distension
1. Medication Side Effects: You mentioned taking over-the-counter medication (新露露) for symptoms of chills and body aches. Some medications can have anticholinergic effects, which may lead to urinary retention or difficulty in bladder emptying. This could contribute to the sensation of bladder distension. If the medication you took contains ingredients that affect the bladder or urinary tract, this could be a potential cause.

2. Urinary Retention: Even if you are not experiencing pain or increased frequency of urination, it is possible to have urinary retention, where the bladder does not empty completely. This can lead to a feeling of fullness or distension. Factors such as anxiety, certain medications, or even temporary muscle spasms can contribute to this condition.

3. Infection or Inflammation: Although you have not reported any pain or burning during urination, a urinary tract infection (UTI) or bladder inflammation could still be present. Sometimes, infections can cause a feeling of fullness or pressure in the bladder without the typical symptoms of urgency or pain.

4. Bladder Dysfunction: Conditions affecting bladder function, such as interstitial cystitis or bladder overactivity, can lead to sensations of fullness or discomfort. These conditions may not always present with classic symptoms, making them harder to diagnose.

5. Dehydration or Concentrated Urine: If you are not adequately hydrated, your urine may become concentrated, leading to increased bubbles or foam. This can also contribute to a feeling of bladder fullness.


When to Seek Medical Attention
Given that the sensation of distension has persisted for two days, it would be prudent to consult a healthcare professional. They can perform a thorough evaluation, which may include:
- Urinalysis: To check for signs of infection or other abnormalities.

- Ultrasound: To assess bladder volume and check for any abnormalities in the urinary tract.

- Medication Review: Discussing any recent medications you have taken and their potential side effects.


Management and Recommendations
1. Hydration: Ensure you are drinking enough fluids to help flush out your urinary system. This can also help alleviate any potential irritation in the bladder.

2. Monitor Symptoms: Keep track of any changes in your symptoms, including urination patterns, pain levels, and any new symptoms that may arise.

3. Avoid Self-Medicating: If you suspect that the over-the-counter medication may be contributing to your symptoms, it is advisable to stop taking it and consult with a healthcare provider for alternatives.

4. Follow-Up: If the sensation of distension does not improve or worsens, seek medical attention promptly. Persistent symptoms may require further investigation to rule out any serious underlying conditions.

In summary, while bladder distension can arise from various causes, it is essential to approach this symptom with caution. Consulting a healthcare professional will provide you with the best guidance and ensure that any potential issues are addressed appropriately.
