Sorry to hear that you're suffering, and to the point that your project is stalled!
I've had hand aches, wrist aches, but none of them compare to the searing pain I've had the past two weeks. It runs upwards from my elbow to a few inches below my shoulder, in the muscles, like a butcher knife is stabbed into my arm.
But I know how you feel ("should I wait, or should I see a doctor?"). I'm not very good about seeking medical attention...I suffer with pain until it goes away...but clearly, that's really not the way to address pain.
I agree with all other comments...you should see a doctor. Perhaps there is a medication, or dietary changes, that will relieve your joints of pain and the stress that's causing the pain.
A baby blanket, gifted to the mommy, when the baby is even one-year old, will be a WELCOMED GIFT.
Give it to the baby as a 6 month's birthday present, or a one year birthday present!
