Parasitic infections can indeed be a source of significant concern and anxiety, especially when symptoms such as itching, unusual bowel movements, and abdominal pain arise. Based on your description, it seems you may be dealing with a potential parasitic infection, possibly involving pinworms (Enterobius vermicularis) or even tapeworms (such as Taenia species). Let’s break down the symptoms, diagnosis, and treatment options.


Symptoms of Parasitic Infections
1. Itching around the anus: This is a classic symptom of pinworm infection, particularly at night when the female pinworms lay their eggs. The itching can lead to scratching, which may cause further irritation and potential secondary infections.

2. Visible worms or eggs: Finding a white, curled worm in your stool or on your body can be alarming. Pinworms are small, white, and can be seen with the naked eye. Tapeworm segments, known as proglottids, can also appear in the stool and may resemble small, flat, white pieces.

3. Bowel habits: Your report of having bowel movements every two days, along with gas and foul-smelling stools, could indicate a disruption in your digestive system, possibly due to a parasitic infection.
4. Abdominal pain: This can be attributed to various factors, including poor posture, digestive issues, or the presence of parasites.

Diagnosis
The diagnosis of parasitic infections typically involves:
- Stool examination: This is the most common method for diagnosing intestinal parasites. A single stool sample may not always be sufficient, as eggs or segments may not be present in every sample. Multiple samples over several days may be necessary for accurate diagnosis.

- Tape test: For pinworms, a piece of clear tape can be pressed against the skin around the anus to collect eggs, which can then be examined under a microscope.

- Blood tests: In some cases, blood tests may be conducted to check for eosinophilia, which can indicate a parasitic infection.


Treatment
1. Medications: The use of mebendazole, as you mentioned, is a common treatment for pinworm infections. It works by preventing the worms from absorbing glucose, effectively starving them. If symptoms persist after treatment, it may be necessary to consult a healthcare provider for further evaluation and possibly a different medication or a repeat treatment.

2. Hygiene measures: It is crucial to maintain good hygiene to prevent reinfection. This includes washing hands thoroughly after using the bathroom, keeping fingernails short, and washing bed linens and pajamas regularly.

3. Follow-up: If symptoms continue despite treatment, further evaluation may be necessary, including additional stool tests or imaging studies to rule out other conditions.


Anxiety and Health Concerns
It’s understandable to feel anxious about these symptoms, especially when they persist. Anxiety can exacerbate physical symptoms, leading to a cycle of discomfort. If you find that your anxiety is affecting your breathing or overall well-being, it may be beneficial to speak with a mental health professional or counselor. They can provide strategies to manage anxiety and help you cope with the stress of your health concerns.


Conclusion
In summary, the symptoms you are experiencing could be indicative of a parasitic infection, most likely pinworms or potentially tapeworms. It is essential to follow up with your healthcare provider for further testing and treatment if symptoms persist. Maintaining good hygiene and being proactive about your health can help alleviate some of the concerns you have. Remember, you are not alone in this, and seeking help is a positive step towards feeling better.
