Left Lower Abdominal Pain Radiating to the Left Flank

There is a dull pain extending from the lower left abdomen to the left flank?

Hello, doctor! Due to a busy work schedule, I forgot to drink water and use the restroom.
A month ago, I discovered blood in my urine.
I later visited a doctor and was prescribed antibiotics (CIROK 500MG TAB and CLEANXATE 200MG TAB), and the symptoms have since resolved.
Subsequent urine tests returned normal results.
Last week, I suddenly experienced a dull pain in my lower left abdomen (lasting 1-5 seconds at times).
This week, the pain in my lower left abdomen has started to radiate to my left flank.
I am experiencing symptoms of frequent urination, abdominal bloating, pain in the left abdomen and left flank, occasional dizziness, and my urination seems less smooth than before, but it is not painful.
My diet is normal, and I have maintained a stable weight without gain or loss.
I would like to know what disease this might be.
Thank you!

Drink less water, which can lead to kidney stones or infections.
If you have symptoms, please get an ultrasound or X-ray and a urinalysis at the obstetrics and gynecology or urology clinic.

Hello! Thank you for reaching out with your concerns regarding the left lower abdominal pain radiating to the left flank. Based on the symptoms you've described, there are several potential causes that could be contributing to your discomfort.

Firstly, the history of blood in your urine (hematuria) and the subsequent treatment with antibiotics suggest that there may have been a urinary tract infection (UTI) or possibly a kidney-related issue. Although your urine tests returned to normal, it’s important to consider that some conditions can cause intermittent symptoms. The left lower abdominal pain that radiates to the left flank could be associated with several conditions, including:
1. Kidney Stones: The pain you are experiencing could be due to kidney stones, which can cause sharp, severe pain that radiates from the lower back to the abdomen. The pain often comes in waves and can be accompanied by other symptoms such as hematuria, nausea, and changes in urination patterns.

2. Urinary Tract Infection (UTI): Even though your symptoms improved with antibiotics, it’s possible that the infection was not fully resolved or that another infection has developed. UTIs can cause abdominal pain, frequent urination, and a feeling of urgency.

3. Musculoskeletal Issues: Given that you mentioned the pain radiates to the left flank, it could also be related to muscle strain or injury, especially if you have been engaging in physical activities or have had any recent changes in your routine.

4. Gastrointestinal Issues: Conditions such as diverticulitis, irritable bowel syndrome (IBS), or even constipation can cause left lower abdominal pain. If there is any associated bloating or changes in bowel habits, these could be contributing factors.

5. Gynecological Issues: If you are female, it’s important to consider gynecological conditions such as ovarian cysts or endometriosis, which can cause similar symptoms.

6. Referred Pain: Sometimes, pain from other areas, such as the spine or pelvis, can manifest as abdominal pain. Conditions affecting the spine, such as herniated discs, can cause referred pain to the abdomen.

Given the complexity of your symptoms, it is advisable to follow up with a healthcare provider for a thorough evaluation. They may recommend imaging studies such as an ultrasound or CT scan to assess for kidney stones or other abdominal issues. Additionally, a urinalysis and possibly a urine culture can help rule out any lingering infections.

In the meantime, ensure you stay well-hydrated, as dehydration can exacerbate kidney-related issues and urinary symptoms. If you experience worsening pain, fever, or any other concerning symptoms, seek medical attention promptly.

In summary, while there are several potential causes for your symptoms, a comprehensive evaluation by a healthcare professional is essential to determine the underlying issue and appropriate treatment. Please take care and prioritize your health!
