Hello,
Brown discoloration of the lower legs commonly occurs due to high pressure in the leg veins, fluid build up,
venous insufficiency,
varicose veins or
hemosiderin deposits.
You are suggested to visit ER, get physically examined, evaluated & assessed so that you can be treated precisely at the earliest. You will have to go through some blood workouts & Imaging tests. In the meantime, you can use support stockings for relieve.
You may need to give your legs rest for a couple of days or opt for a change of job.
To prevent water retention eat less salt, avoid refined carbohydrates, Take food rich in potassium &
magnesium. Take vitamin B6 supplements.
Neglect will result in more serious complications like circulatory, lymphatic or
kidney problems.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
