Good morning, Dr. Jerry E. from New York here!
I'm sorry to hear about your mother's ordeal. It is difficult to see a family member go through that. Things tend to happen quickly and often the medical community does not offer the explanations we need.
When sodium levels are off balance and then rapidly restored with fluids, fluid shifts can occur which allow the fluid to leak out of the blood vessels and out of the cells, into what is called the "third space". She needed the sodium to maintain brain and cardiac function, but all of the extra fluid that the sodium was dissolved in had to go somewhere! On your mother this appeared as swelling in her legs. Fluid tends to go where gravity will let it sit, and this can cause varicose (over-stretched) veins that are prone to bursting. I wouldn't be surprised if her legs which are flaky are also somewhat red. The treatment for this along with careful fluid management is to have her legs elevated when she is not walking around and to wear compression stockings (Available at a pharmacy).
Do you have any other questions?
No, the lasix should not be stopped completely. That could cause fluid on her lungs and swelling (fluid) everywhere. The dosage should be monitored by her doctor. If these answers have helped you, please click accept.
