I have had good luck with a topical ointment called Traumeel (Company name is Heel) for joint pain. I think it kept me mobile when my Crohn's arthritis flared between Thanksgiving and Christmas. I thought I might try arnica cream or gel next, some customers of mine tell me it works fine, and it is less costly. I also use heat, but that's not so easy when you are up and around. As for the nose sores as well as mouth sores and cold sores, I find those heal far quicker when I take probiotics and L-Lysine. I can't help with the breathing, I always chalk it up to my asthma. I agree the breathing exercises mentioned above might be helpful, whatever the cause, they are similar to ones used by respiratory therapist.
