Tight and sore as in the wrist flexors? Or the joints themselves (e.g. carpals) are hurting?
Warming up the joint well before training is important. Just move those things around in every possible way you can imagine a bunch (that's my scientific approach). Once warm, stretch the flexors thoroughly. During your training, you can keep stretching, moving and shaking out the wrists between sets. If you decide to wear bands, for now stick with loose-ish ones that simply are there to keep the joint warm. Avoid taping or support bands unless absolutely necessary (and even then, see if you can save them for lifting 85-90% and up loads) because that can start sending problems down to the elbows and shoulders.
