sorry to hear of your accident, I've never knew that it was possible for high pressure air to enter through the pores. I nursed a lady once who had surgical emphysema, it was caused by a chest drain. The air escaped from the chest drain into the tissues of her body. It was wierd because as she spoke her voice resonated because of the air in her tissues. When her skin was touched it also resonated like a drum, and the air could be felt popping under the skin. When the chest drain was removed the air began to dissipate. Have you had any odd sensations like that with your finger? I bet your not able to bend your fingers because of the swelling.
Good luck, hope you get better soon.
