Trigger Finger

My trigger finger is back to haunt me again, sigh* I guess I must have been using my left hand to grip too much things. I had it close to a year ago, when I couldn't straighten the middle finger of my left hand. It was locked in a 90 degree position, bent. I had to use my right hand to straighten it. Back then I went to see the doc n he prescribed me with anti inflammatory medicine. Took them n gradually it subsided. However it didn't fully recover because after that whenever I bend my finger, I can hear the clicking sound. As it didn't affect my daily life, I didn't bother about it. Now it's back to haunt me again. I think it is really time to heed the doc's advice, to get a steroid jab. My mom got that too n she went for the injection a while back. I did not dare to do it because I can't imagine imjections into my bone. Freaking me out esp when it's on the finger. How now brown cow?
