Help losing distance

[Tduncan2000]

I am a 5ft 3in tall 16 year old golfer. At the beginning of the year  I was hitting my irons decent and pure. I got a lesson from my local pro and he helped me but now all its done is hurt after about a week of working for me. I hit almost every iron the same distance now. I've lost 25 yards on each one since beginning of year.  even on a pure strike.

Do you have a video you can post?

Seconded.  But without one, assuming all evidence was given, it sounds like the issue lies with the instructor.  Maybe try a different instructor.

Having had a time when this was the case, I'd suggest you look at your angle of attack (the steepness you come into the ball). I used to hit down so much (-8 degrees with a driver...) that I tended to make every club past a 7 iron essentially the same loft, meaning there was only about a ten yard gap between 7 and 4 iron. If that sounds like it rings true, I'd check that. 

Also, just ask the instructor whether that'd be what he/she would expect or get them to put you on a launch monitor. If they can't explain it to you, then definitely change the instructor. I'd give them the chance first, as they may just be working on a longer term schedule than you thought - I went through a period with a 3/4 swing essentially to tighten up tempo and timing and now I'm back to a full swing, I've gained at least 10 yards on where I was before. Again, though - you'd hope they'd have explained it to you first.
