Anti-inflammatory drugs can inhibit muscle growth

Adequate recovery efforts, while not as immediately effective as NSAIDs, can help if done consistently over the long-term.  By recovery efforts, I mean:

-Eating a sound diet that includes enough of each macronutrient;

-Getting 8+ hours of sleep EVERY night;

-Foam rolling, or using a lacrosse ball for the tricky spots;

-Epsom salt baths;

-Contrast showers;

-Icing after (please not before) use.

Different methods work for different people.

Not to mention it thins the blood. I know a kid who was taking so much pain/anti inflammatory mediation in order to keep playing (at age 14) that he fell down and hit his nose (in a game) and got such a bad bloody nose he had to have it cauterized to stop the bleeding. He ended up blowing out his elbow at the same time, ironically.
