Re: Tingling and pain in fingers..
Pareezay, your injury is amongst those that are most commonly misdiagnosed... people think that because they have pain in the wrist/hand area, it must be CPT, but it equally could be a inpingement of the ulna nerve, cubital tunnel syndrome, some form of thyroidism, arthiritis or even tingling/numbness due to obesity (i'm not implying you are ;))
I really don't think you have CTS.... you need to go to the doc and they'll do some quick tests on you..... and provide you with topical or oral medicine to reduce the inflammation in the affected area... no need for a splint.......yet :)
For the meantime, i would suggest you take an analagesic obtained over the counter, such as oral Ibuprofen, or a topical cream such as Diclofenac, giving that you're not allergic to it. :)
