Please help with out of pocket Vascular Doctor

I will be 69 years old in 2 weeks. I have been suffering financial hardship and severe complications from a heart valve replacement on June 22nd, 2023 when I was close to death because I had only one heart valve functioning and it was narrow and restricted due to hereditary Bicuspid Prolapse Heart Valve disorder. I had been previously ill on and off for 7 years. I have always helped others in many ways but rarely asked for help myself. This past year I have had help from only 4 people who have shown their concern for me not only financially but in many other ways. In less than 2 months it will be a year I have been dealing with this chronic disorder in my left leg. It leaves me immobile and in severe pain constantly. I don’t qualify for disability or unemployment. I can’t sleep, eat, or do my normal activities. Worse I have not worked for over 8 months consistently and as a Psychotherapist my heart is broken. This has left me in destitute, financial ruin and I can’t pay my bills. Here is my current delema:

I am not getting the care I need from my insurance Kaiser. The doctors don’t know what is wrong and have given up. I have done research and am trying everything because things are getting worse. I don’t want to lose my life or my leg. I have requested a Vascular Doctor several times but this has been denied. I believe I have what is called “lymphedema.” Untreated it can lead to amputation or even Cancer.

I am asking anyone who can to please donate anything so I can pay out of pocket for a Vascular Doctor and also pay for evaluation and treatment.  Please help me.

I must get better and return to work.
