Soft Lumps on the Outer Calves: Are They Lymph Nodes?

Prominent lymph nodes in the calf?

Hello doctor, I would like to ask about two small round bumps that appear on the outer sides of both of my calves when I squat down or exert force.
They feel soft to the touch and I don't particularly feel any lumps, but when I relax my legs or stand, they are not noticeable and I can't feel anything unusual.
Could this be lymph nodes? I have noticed them for over 10 years, and they haven't grown larger or caused any pain.
Is this normal? Do I need to go to the hospital for an examination? Thank you.

Hello, based on your description, it could be a lymph node or a lipoma.
It may be necessary to seek a direct consultation to determine which one it is.
I recommend visiting a plastic surgeon or a family medicine physician for confirmation.
Thank you for your inquiry.

It sounds like you have some concerns regarding soft lumps that you have noticed on the outer sides of your calves, particularly when squatting or exerting yourself. Based on your description, these lumps appear to be soft, round, and not painful, and they become less noticeable when you are standing or relaxed.
First, it is important to clarify that lymph nodes are typically not located in the outer calf area. Lymph nodes are part of the lymphatic system and are generally found in clusters in areas such as the neck, armpits, and groin. In the lower extremities, lymph nodes are primarily located in the groin region. Therefore, the lumps you are feeling in your calves are unlikely to be lymph nodes.

Given that these lumps have been present for over ten years without any change in size or pain, it is possible that they are benign structures. They could be related to various anatomical features, such as:
1. Fatty Tissue (Lipomas): These are benign tumors made up of fat cells. They are usually soft, movable, and painless. Lipomas can occur anywhere in the body, including the legs.

2. Muscle Tissue: Sometimes, muscle fibers can create a noticeable contour or bulge, especially when the muscle is contracted during activities like squatting.

3. Tendon or Fascia: The soft lumps could also be related to the tendons or fascia in the area. The fascia is a connective tissue that surrounds muscles and can sometimes be felt as a soft lump when the muscle is engaged.

4. Cysts: Occasionally, small cysts can form in the soft tissue, which may feel soft and movable. These are usually harmless unless they become infected or cause discomfort.

Since you have mentioned that these lumps have not changed over a long period and do not cause you any pain, they may not be a cause for concern. However, it is always a good idea to consult with a healthcare professional if you have any doubts or if there are changes in the characteristics of the lumps, such as an increase in size, pain, or any other new symptoms.

In terms of whether you should seek medical attention, if you are feeling anxious or uncertain about these lumps, it would be beneficial to have them evaluated by a healthcare provider. A physical examination can provide reassurance and help determine if any further investigation, such as imaging studies, is necessary.
In summary, while the lumps you are experiencing are unlikely to be lymph nodes, they could be benign structures such as lipomas, muscle tissue, or other soft tissue variations. If you have any concerns or if there are changes in your symptoms, do not hesitate to reach out to a healthcare professional for a thorough evaluation. Your health and peace of mind are important, and a medical professional can help clarify any uncertainties you may have.
