Water bubbles in the legs, also known as leg edema, are caused by a weak heart that cannot pump blood properly or aged veins that cannot move fluid effectively. Symptoms should be discussed with a doctor, who may prescribe medications like nitroglycerin patches, diuretics, or potassium supplements to reduce excess fluid. Small water bubbles can be drained and covered to prevent infection, but larger bubbles risk exploding and causing serious wound infections if not treated promptly.

1. Water bubbles in the legs
Water bobbles in the leg are caused by a bad heart, which
it can't pull up the blood up, or the veins become weak
with age and can't move fluids up the body, if you have
that kind of problem, talk to your doctor to get
nitroglicerin patches or pills for your heart (if you have
irregular heart beating) and pills to get rid of excess water
in your body, Torsemide, Spironolactane and if that fails,
torsemide which is a very strong diuretic (you may also
will need potasium pills, because if you pee too much,
your potassium levels will be very low)

2. Get rid of this water bobbles as soon as possible,
pinch them open when they are very small and let
them drain. Cover the wound to protect it and change
bandages often. If you allow them to grow to big, will
grow to around 30 inches in diameter, will explode
and will cause a staff infection on the open wound, or
other nasty infection that can be very bad.
