I have been working out pretty intensely with relatively no break for 2 years. I lost 85 lbs total.?

I have recently hit my target weight of 155lbs and aggressively changed my workout routine to break through my plateau. It has been working I continue to lean and bulk up. My current diet consists of about 1600-1800 calories a day 150-170 grams of protein less than 30 grams of fat, and less then 65 grams of carbs. I lift weights for an hour everyday and then do 45 mins of cardio after wards. I now take L Carnitine to help me burn the remaining excess fat. A few days ago my compressor was falling off my workbench in my garage, I went to save it and grabbed the handle with my left hand. Immediately after letting go I felt an extreme pain in my wrist. I can move my wrist back and forth fine but can not turn it AT ALL. I know I am not going to be able to lift weights for at least a week. I will continue to do cardio. Should I increase my calorie intake to maintain the muscle I have, or keep it the same? Also any idea what is wrong with my wrist?
