Hello from JA
I am a double board certified doctor and I can help you with this. I have a much different answer for you.
The symptom you describe related to sleep is common for venous insufficiency, not liver disease, not heart disease, etc. You do not give any history consistent with these diseases.
There is no basis for us to say this is genetic at this point, and I must point out that the danger here is that venous stasis predisposis you to clots in the legs.
The test needed is an ultrasound.As long as there are no clots, the treatment is exercise, weight loss as indicated, and compression stockings.
In fact, until you have an exam and testing, none of the home treatments recommended are indicated.
Please let me know if you have further questions.
Use reply as needed.
Please do not forget a positive rating.
