I have shooting pain in my left thumb and index finger, thumb finger is turning blue in cold but it returns to lil red in hot or sunny conditions. Iam feeling so much of itching and pain particularly at night. I have done some blood testing camps where i used this hand and worked repetedly for more than 800 patients in last 1 month. I used these fingers to press the patients finger. Iwas pricking the patients hand very little and was pressing very stronhly from my hand.
