With reading your history, I presume that you might be having varicose veins
in right leg.
The bumps are seen in standing position and disappear when leg is elevated.
The bumps are felt below the skin.
All these points direct the mind to believe that you might be having varicose veins.
You consult surgeon for firm diagnosis, after investigations.Sclerotherapy
and surgical intervention may be the treatment by expert.
I think you may have good result.
