"I read the linked article about French horn players awhile back and found it very interesting re lip swelling from certain meds, salts, supplements. Interesting that some players had found that taking Ibuprofin (Nsaid) before playing was helpful."
Oy! If a person's (for example) hands are stiff due to disease, old age or most commonly, both, then an OTC such as ibuprofen can be handy. However, I think most (if not all) would agree that the need for a medicine to perform at one's optimum level when it's not needed is a sad state. However, if you want to enhance performance, I have the recipe.
Find a hot looking audience member and play to them. That will enhance playing more than a whole bottle of Advil "and" you might just get lucky! It's tough to argue with lucky.
