The transverse processes that you note are not generally a painful problem. This is called a sacralization of L5 and these enlarged processes actually protect this level and prevent pain from occurring.
The general start of a program to treat lower back pain includes physical therapy and medications. I am unfamiliar with the medication you note but many different countries name the same medication with different labels.
There is a standard protocol to treat back pain. If rehabilitation is unsuccessful, imaging studies including an MRI would be called for. Injections can be helpful and finally if nothing works, a referral to someone like me would be indicated.
