Question) My calves have been feeling swollen lately. Why is that?

Lately, my calves have always felt heavy and swollen. They're not noticeably swollen, but they feel especially sore and tight in the evenings. It gets especially worse after sitting or standing for long periods, and it's more uncomfortable in the afternoon or at night than in the morning. Rubbing my legs and elevating them seems to help for a while, but the recurring feeling is bothersome. My exercise level and weight haven't changed much, but I'm wondering if it could be due to hydration, blood circulation issues, or hormonal factors. If anyone has experienced similar symptoms, please share what caused them, whether you've had to seek medical attention, and if you have any management methods that have actually helped.
