It's quite common for withdrawal symptoms to hit one side or the other. In my time here, I've not seen that the left or right side is more prevalent, it depends on the individual. I'm glad you can see a connection between the cessation of your pain when you reinstated, this told you that the Klonopin was the reason you were hurting. The fact that it ceased to work as effectively as it once did is due to your body reaching tolerance to it. If you were to increase your dose to say, 3 mgs, you'd likely feel better, but only for a short time. If you don't continually increase your doses, your body will in actuality be withdrawing, this is why you hurt.
We're not here to try to convince you that you're suffering from benzo withdrawal syndrome, this is something you have to come to believe on your own. We're here to help you cope with it, to understand it better and to support you in your desire to be free from it.
I did a cold turkey which is pretty much what you did the first time. It took me 14 months to heal, but I did! When you're free from the drug and the withdrawal symptoms, you'll feel 100% better, this I can promise.
