Can someone please help me ????

Hello ,
    My name is Lisa Andrews and Iam 31 Years old. When I was born my hands had a defect and my thumbs didnt develop properly, so when I was 3 years old (aprox) I had a Pollicization opperation on my left hand, at Sheffield Childrens. My right hand was left alone but my thumb hasnt really grown, and is really small. Im unsure what my condition is called as my mum was only give very basic information when I was born. This has never bothered me (apart from the small odd bits of childish name calling) It has never stopped me from doing anything, Iam Right handed, and work as a succesful Hairdresser with my own salon, so without a usable thumb I use my hands alot differently then other people.
           A few months ago my middle finger started getting pins and needles, then it went completly numb and has stayed like that. My ring finger has now occasionally started with pins and needles. I have been to my GP who thinks it may be Carpol Tunnel , and has rerferd me to the Northern General Hospital to see a hand surgen.
           I know its a long shot but I wondered if you knew of anyone who has the same difference as me, and if you knew of any complications that my hand defect can cause in later life or is Carpol Tunnel one of the things that i can expect to get.
            Iam really worried as I dont want this to get any worse as I have my business and very much enjoy my work .I have always been a very strong willed person that is determined to prove that just because I dont have a thumb I can do anything I want, and would be devestated if I had to stop for reasons that I cant control. I would very much appreceaite it if you could pass any information on to me.

        Thank You so much for your time,
           Lisa Andrews.
