The usual procedure is to try all conservative measures first, and if they do not relieve your pain, then surgery can be an option.
The longer you allow the nerves to be compressed the more likely you will develop permanent nerve damage, which is something you don't want to happen.
Have you been diagnosed by a spine surgeon?
Have you had surgical options given to you?
There is really no documented scientific evidence that "decompression therapy" actually works, and there have been cases that it worsens problems as well.
I do know a couple of people that have given it a try though. Very expensive, insurance doesn't usually pay for it, and if pain relief was achieved, it was very very temporary, lasting a few hours to a day or to and then another session was required to relieve the pain.
In the end, all 3 people needed decompression surgery to relieve the pain.
M1ch, you are very early in your post op from discectomy to be able to determine if it was successful for you.
It is quite common for some of the pain to slowly return a few weeks after discectomy surgery. What you are feeling, no doubt, are the nerves beginning to heal and they create similar to same pain for a period of time until the settle down.
Once they settle down, most times the patient has complete relief or almost complete relief of the pre surgery pain.
It's exactly what happened to me with my surgery and by 6 months post op, I was completely pain free.
Good luck to both of you.
