Hello i got a large wood splinter embedded in my forearm today.it is very aggravating and painful already any advice on getting it out should i wait?

Some basics: If this is interfering with your daily activities you should take time to seek care & have it removed. Although some may consider this minor, I have seen these become infected & lead to significant impairment. Tetanus & other infections are possible. It often takes two good hands & experience to get these out. Some require minor surgical procedures for extraction.
