on the Luklinksi clinic in london, please see the link below to a prior post with information about the clinic.
Also read the link in one of the threads about the clinic. from what that link says it does not sound like a good place to go and based on info from a British investigation.
As for you pain, it sounds like you may have the disc problem again. that can happen after a disectomy.
It is also possible that you have spinal stenosis and have nerves being compressed.
Sounds like it would be a good idea to get another opinion from a really reputable spine surgeon.
An orthopedic surgeon that specializes in spines only would be a good idea to see.
A fresh set of eyes never hurts
You may or may not need more surgery. Only a spine surgeon can answer that for you and you will probably need a new MRI as well.
None of us want to have surgery of any kind, but if it is the only way to obtain any pain relief and return you to a functioning life, then it may be your only choice other than to live with the pain.
Good luck and let us know how you are doing.
