I trapped my toe under the sofa and was pushed backwards jarring. my big toe and it is all red and swollen and tingly what should i do?

Ouch.: It sounds as though you may have damaged either the bones in the toe, soft tissue enveloping the toe or both. The amount of bruising and swelling is usually a pretty good indicator on the extent of the injury. Apply ice and elevate the foot. Check for up and down toe movement and strength. It could be that an x-ray will be needed to remove all doubt as to the severity of the damage.
