Anal Issues: Hard Lump and Pain Concerns Explained - Surgery

Anal issues


Hello, Doctor.
I have a few questions because I have a hard lump near my anus that has persisted for over a month.
When sitting on a chair, there is a painful spot on one side, and it hurts when pressed, but I don't feel pain while walking.
However, I do experience a dull ache when I contract my anal sphincter.
I have seen two doctors; both performed a digital rectal exam and palpation.
One doctor suggested it might be a nerve issue since there was no hard lump felt, while the other doctor said the digital exam was fine, and although they found a painful spot during palpation, they did not find a hard lump.
The examination was done while I was lying on my side, but I can feel the hard lump when standing or squatting.
I asked the doctors if it could be an abscess or anal fistula, and they confidently said it was not possible.
They suggested the pain might be muscular and prescribed pain medication.
I would like to ask the doctor: 1.
If there is a hard lump in the buttocks, could it be missed due to different positions (lying on the side vs.
standing)? 2.
If no hard lump was found during the digital rectal exam and palpation, does that rule out the possibility of a fistula? The doctors were very certain, but since the cause is still unclear, I am a bit worried.

1.
No, the depth of examination during a digital rectal exam is limited.
If there are concerns about other issues that may not have been detected, a colonoscopy can be arranged.

2.
Yes, the diagnosis of anal fistula is primarily based on palpation.
If the examination shows no abnormalities, you may also consider consulting a gynecologist to rule out any gynecological issues.

When it comes to anal issues, particularly the presence of a hard lump and associated pain, it is essential to approach the situation with a thorough understanding of potential causes and the importance of proper medical evaluation. Based on your description, you have experienced discomfort near the anal area for over a month, with a hard lump that is painful when sitting but not when walking. Additionally, you mentioned that the pain intensifies with certain movements, such as tightening the anal muscles.

1. Variability in Palpation: It is indeed possible for a lump or hard area to be palpated differently depending on the position of the patient during the examination. For instance, lying on one side may change the anatomical relationships and the tension in the surrounding tissues, potentially making it more challenging for a physician to identify a lump. This variability can be due to muscle tension, the position of internal structures, or even the presence of fat tissue that can obscure the underlying anatomy. Therefore, if you feel a hard lump while standing or sitting, but it is not palpable during a side-lying examination, it does not necessarily mean that it is not present; it may simply be a matter of positioning.

2. Differentiating Between Conditions: Regarding your concern about whether the absence of a palpable hard lump during a digital rectal exam (DRE) or external examination rules out the possibility of an anal fistula or abscess, it is important to understand that these conditions can sometimes be elusive. An anal fistula may not always present with a palpable lump, especially if it is internal or if the external opening is not readily visible. Similarly, an abscess may not be easily felt if it is deep or if the swelling has not progressed to a point where it is palpable externally.
The fact that two different physicians have provided differing opinions adds to the complexity of your situation. One suggested a neurological issue, while the other indicated muscular pain. This discrepancy highlights the need for a comprehensive evaluation. If the pain persists and the lump remains a concern, it may be worthwhile to seek a third opinion, preferably from a specialist in colorectal surgery or a gastroenterologist who can perform a more detailed examination, possibly including imaging studies like an ultrasound or MRI if indicated.

3. Potential Causes: The symptoms you describe could be attributed to several conditions, including:
- Muscle Strain or Spasm: Pain in the anal region can often be related to muscle tension or spasms in the pelvic floor muscles.

- Hemorrhoids: Swollen blood vessels can sometimes feel like lumps and cause discomfort.

- Abscess or Fistula: Although your doctors have ruled these out, they remain possibilities that should be considered if symptoms persist.

- Skin Conditions: Conditions such as hidradenitis suppurativa or other dermatological issues can also present as lumps in the anal area.

4. Next Steps: Given your ongoing symptoms, it may be beneficial to:
- Keep a Symptom Diary: Documenting when the pain occurs, its intensity, and any associated activities can provide valuable information to your healthcare provider.

- Consider Imaging: If the lump persists and is concerning, imaging studies may help clarify the diagnosis.

- Explore Physical Therapy: If muscle tension is suspected, pelvic floor physical therapy may provide relief and help address any underlying muscular issues.

In conclusion, while your current physicians have provided their insights, the complexity of anal and perianal conditions often requires a multidisciplinary approach. If your symptoms continue or worsen, do not hesitate to seek further evaluation to ensure that you receive the appropriate care and peace of mind regarding your health.
