Post-Surgical Scar Pain and Digestive Changes After Fistula Surgery - Surgery

More Info

---

After undergoing fistula surgery two years ago, it is not uncommon to experience some discomfort or pain around the surgical scar, especially during activities like walking or in warmer weather. This pain can often feel like a burning or stinging sensation, similar to what you described as "破皮似的疼痛" (skin-breaking pain). Such sensations are typically due to the formation of scar tissue, which can be sensitive to changes in temperature, pressure, or movement.
Scar tissue is different from normal skin; it is less flexible and can sometimes adhere to underlying tissues, leading to discomfort during physical activities. This is particularly true if the scar is located in an area that experiences a lot of movement or stretching. Over time, many patients find that the sensitivity of their scars decreases as the tissue matures and becomes more pliable. However, if the pain persists or worsens, it is advisable to consult with your healthcare provider to rule out any complications or underlying issues.

Regarding the black, hair-like structure you mentioned near the surface of the scar, it could potentially be a hair follicle that has not healed properly or a small piece of suture material that has become embedded in the scar tissue. If left untreated, it may lead to irritation or infection, so it is best to have it evaluated by a medical professional. They can determine whether it needs to be removed or if it poses any risk to your health.

As for your digestive changes, the transition from having loose stools to more formed bowel movements can be influenced by several factors. After surgery, especially one involving the gastrointestinal tract, it is not uncommon for patients to experience changes in bowel habits. This can be due to a variety of reasons, including alterations in diet, changes in gut motility, or even the body's adjustment to the surgical changes.

If you had been consuming less food prior to the changes in your bowel habits, this could certainly contribute to the consistency of your stools. A diet low in fiber can lead to softer, less formed stools. Conversely, as you began to eat a more balanced diet with adequate fiber, your bowel movements may have normalized. Additionally, stress, hydration levels, and physical activity can also significantly impact bowel regularity and stool consistency.

If you continue to experience irregular bowel habits or if you have concerns about your digestive health, it would be wise to consult with a gastroenterologist. They can perform a thorough evaluation, including dietary assessments and possibly diagnostic tests, to determine if there are any underlying issues that need to be addressed.

In summary, while some post-surgical discomfort and changes in bowel habits can be normal, it is essential to monitor your symptoms and seek medical advice if they persist or worsen. Regular follow-ups with your healthcare provider can help ensure that your recovery continues smoothly and that any potential complications are addressed promptly.
