the worst part in my case, is if you have any kind of back problem , having to stay on my back and keeping the
leg straight for 6 or more hourse was the real problem. For the next 3 days I had a bad back pain, and ended up in the ER with severe neck muscle spasms.
( But I allready have pre-existing back pain , chronic that I take Methadone for, and the Methadone did nothing for this pain.) Remember, I may be the exception to the rule.
Good luck if you decide to have the test.
