Dear friend, welcome to HCM.
all these are due to varicose veins
and increased venous pressure , so worse on walking more.
thses tablets will NEVER work.
you do an ultrasound
of veins to rule out S-F incompetence at grioin level.
use elastic crepe bandages (learn under supervision ) whole day to keep veins down . and keep legs elevated on pillows when lying down. this is genuine medical advice
which works.. nothing else. ocassionally a valve repair at the groin vein mey be necessary.
good luck !
Take care and pl. keep me posted on your progress.
