Although serious injury is rare, bruising and soreness are common when you have blood drawn. You should drink plenty of water the day of the draw, keep your arm warm beforehand and dangle your arm to increase blood pressure at the site. After the procedure, icing the area and stretching the muscles of your arm may help reduce any referred pain.

Before Any Exercises
Before stretching or exercising after a blood draw, be sure that it is safe to do so. The puncture site should not be bleeding and pain should be minimal. If there is persistent dizziness or extreme pain present, contact a doctor immediately. Always ask a doctor or medical professional if stretching is appropriate after any medical procedure.
Standing Bicep Stretch
This stretch will improve arm circulation while stretching the biceps and shoulders. Stand with feet hip-width apart. Clasp your hands behind your back and raise the clasped hands up from the sacrum slightly. The thumbs of both hands should be facing down toward the floor and the arms fully extended. Keep a slight bend in the arms to avoid locking the elbows. Gently lift the hands up toward the base of the skull while pulling the shoulder blades together to support the chest. When you have reached a comfortable stretch, hold for a count of 15 pain-free seconds.
Arm Across Deltoid Stretch
This stretch focuses on the deltoid muscle located on the upper part of the arm. Standing with feet planted firmly on the floor, hold one arm straight in front of you. Move the arm across the chest, holding it straight, palm facing down. With the other arm, pin the stretched arm to the chest just above the elbow. Use the bent arm to pull the stretched arm in toward the body. This will automatically straighten the stretched arm further. Hold the stretch for 15 seconds and release.
The tricep muscle is located on the back of the arm, opposite the bicep muscle. To stretch the triceps, stand with feet apart and extend the arm above your head -- fingertips pointing up toward the ceiling. Bend the arm at the elbow, resting your fingers -- palm down -- on the upper back. Only stretch as far as you are comfortable -- resting the hand on the back of the neck is acceptable as well. Take the other hand and push the elbow gently as the hand of the stretched arm moves further down the spine for a deeper stretch. Hold for 15 seconds and release, taking care not to overstretch.
