I request an appointment

From Dec 2015 to Aug 2016, I attended your clinic for CTS in my left hand . After 2 lots of cortisone (I think) injections, the symptoms cleared and you discharged me. About 6 months ago, the symptoms returned in my left hand. I waited until now in the hope of improvement but there is none. I have completed a pain/symptoms questionnaire. I actually did 2 but in he first I made mistakes but could not go back; I recorded pain for numbness - I have no pain. Should I go through my GP or is it OK to contact you direct?
