Hi, Thanks for using HCM.
Too much standing and walking can cause vericose veins. But there wont be bruise
. So there may be some injury
causing bruise and swelling. Keep observing it and if you feel like vein dilating and visible in legs or any ulcer in legs then this may be due to vericose vein. Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take care.
