Pins and needles would be from nerve involvement, which could be from a swollen or overused muscle/tendon compressing your radial nerve. It could also be back-related... From your brachial plexus off of your spine. Have you hurt your back recently? Just sounds like a nerve being compressed from somewhere.

Is there no improvement at all with the anti-inflammatories? Is there any position you can rest your hand or arm in that decreases the pain/pins and needles? It could be how you are sleeping at night if it's worst in the morning.
