I have several Tarlov Cysts and my local does not believe they cause pain, I have had then since I was in a car accident in 2008, MY LIFE AS I KNEW IT HAS GONE, The pain is in my back. The burning sensation goes down both legs mainly my right, I cannot sit or stand or walk for long, otherwise I pay for it and end up laying on m,y side on the lounge for at least a couple of weeks, I am 53 and cannot pick up my grandchildren The sensation of having a tight burning elastic band around my right ankle is common, I cannot sleep, My doctor insists that they do not cause anything, I need help. I am a pensioner I cannot afford to pay you until I receive my pension, I am so very sorry
Hi I am Chat Doctor. .  In my opinion I agree with your doctor the cysts itself does not cause pain but if swelled or increased in size could cause some nerve or vascular compression symptoms like sciatica which causes your burning sensation of your back and legs.  It can cause muscular or ligament weakness which I think happened with your right ankle.  In most of the cases they may need no treatment, symptomatic treatment with Advil tab when needed may help.otherwise the only permanent treatment is surgical excision which I think you won't need unless your case became more severe.
