I think the thing that will help you the most is seeing the pain specialist. They will probably increase the doseage of medicine or all together change the meds you are on along with the steroid injections.
The surgeon will be the mechanic to fix the broken parts but the pain doctor is the guy doing the detail work on the car. He/she is the person that is going to make your life livable again.
If by chance the meds you have now are not working at all, you may be able to get in to see the doctor that prescribed the meds to you first. Maybe they can increase the doseage or change the meds, give better hands on advice.
The best advice right now is to hang on and realize that there are treatments that will help you in the works and you are going to be helped soon. Do not give up hope.
Keep us informed,
