I recently started going to the gym about a month back. Being a skinny 17 year old, I wanted to get atleast a little bigger before I headed off to college. My routine consists of squats, deadlifts, bench press, military press and power cleans alternating on M/W/Th. However about two weeks back I suppose I pushed myself too hard on the squats and loaded too much weight without having proper form. What happened was that after squatting down, trying to come back up was extremely difficult. Around parallel my right knee seemed to have locked up. I ended up dropping the weight and after that my right knee has had a dull aching pain in it. It's gotten worse since I've seen my general practitioner who did a test on my right knee. I have taken a break from squats for a week now but I'm still doing the rest of my exercises.
I experience a dull aching pain around my right kneecap area after:
1. waking up and walking
2. going up/down stairs
3. getting up after sitting in a chair for a while
My knee also feels a little weak when I am standing on it.
I would appreciate it if a doctor confirmed what I suppose is patellofemoral pain syndrome and what I should do in terms of treating it. Thank you!
