Desi Hi..
If they are not working don't have em.
No one procedure works for everyone and blocks usualy only work for so long, the time frame we stress so much is so that you can at least get some treatment started early.. problem is we are all so diffrent as to what works and what dosnt, though my blocks stopped working I know they helped some.. but as I say if its makin you worse don't do it.

It is also a fact that invasive procedures are a risky thing for us I have learned to just say no.

hugs hon,
Sandra
