Patient's Query

Hello doctor,

One of my legs appears more muscular and wider, especially the calf. I am unsure if this is new or has always been the case, as I noticed it today. What could this be?

Thank you.


Welcome to icliniq.com.

It is not uncommon to have slight differences in muscle size and symmetry between the two sides of the body. However, if you have recently noticed a significant difference in muscle size and width between your legs, it may be worth investigating further. Various factors can contribute to asymmetrical muscle development, such as differences in physical activity, exercise habits, or natural variations in muscle growth. It is possible that you may have unintentionally favored one leg over the other during activities or exercises, leading to differences in muscle size. Additionally, reflecting on any past injuries or issues that may have affected one leg could provide insights into the difference in muscle size. If you have a history of injury or trauma to one leg, it could potentially impact muscle development.

Thanks and regards.

Patient's Query

Thank you doctor for the reply,

I had a really bad ankle sprain on the leg four weeks ago, and it is still quite tender. Could this be related to the calf? Additionally, I have been off work for six weeks because, previously, I was highly active as a teacher, working and being on my feet for 12 hours a day. As a result, I have spent more time resting and am sleeping longer, up to 10 hours in bed, whereas previously, I slept for around 6 hours a night. Could this also impact the muscle?


Welcome back to icliniq.com.

The answer to both questions is yes. However, if tenderness is present, you should immediately get an X-ray of the ankle and a Doppler to rule out lower limb edema. While it is highly unlikely if you can walk without any discomfort, it is still better to be sure. Resting more can indeed impact muscles, but it would not cause swelling. Instead, it can lead to thinning of both limbs.
