tingling and numbness returning

Hi Dr Bland,
Its been a while since contacting the department. Just to let you know that I have stiffness in my left and right forefinger and second finger on a regular basis particularly in the morning and when holding a pen for long time. It has been about a year since steroid injection in both hands would you advise another one at this stage? I use Voltarol daily to ease the numbness and the pain ( although the pain is not as bad as it used to be)
kind regards
Richard N
