[|AI|]  Hello, Most of the time injection site irritation and symptoms are similar to what you've described and do tend to get better with time.  The problem is getting reinfected in the same area and this could reactivate you after effects.  I recommend you speak to your doctor about the lack of effect for your pain that these injections have given in the hopes of coming up with an alternative.  I do not advocate my patients that they continue using medications or undergo procedures which no longer seem to be efficacious.  At that point, we look for alternatives.  Hope I have answered your query. Let me know if I can assist you further. Take care.  Chat Doctor.
