Im sorry to hear that you think your flaring up that stinks. Maybe the stabbing pain is from a pinched nerve because their is inflamation? My hands do the same thing...sometimes both of my hands fingers swell and I have a hard time moving them, sometimes just one hand hurts and is swollen, and even sometimes just one finger on one hand is swollen..It is weird.. I dont know about u, but my inflamation for the rest of my joints do that also. I will have pain in my knees for a few days, then wake up and they will feel great, but then for whatever reason my elbows will be in pain and swollen. Its like a guessing game in the morning when I wake up..Where is the pain and swelling today!? I guess i should be thankful that only a few places on my body are in pain at a time..I couldnt imagine if all of my joints hurt like this all at once!! Yowsers..it's hard enough to function already!! I hope u can nip this flair in the bud!!!! Good luck!!
