Thank you very much in taking the time to read my post,
I live near the national football stadium and I hear they have an excellant private Physio deprtment, I'll check them out.
Torn/detatched muscle could be a possibility due to the body mechanics involved during training.
no pain on when I extend backwards with lifted arms
I notice the pain mostly after ive been sitting or lying for a while, i could even do crunches the pain is very specific I suppose that would make the diagnosis for the physio easier
In a trapped nerve, you'd feel pain in more extended area, and it would probably go with some skin tingling.
Can you make a deep breath without a pain, can you lift your hands without a pain?
If there was pneumothorax, you'd feel pain with every breath and move, and on different spots, like in scapula or shoulder.
Two thoughts:
1. hematoma - a blood collection, but this should improve in this time, I guess.
2. torn muscle, or muscle partly detached from the rib - this can't be found with x-ray
When you bend forward - no pain, but what when you extend backwards with lifted arms? If pain, this speaks for torn muscle. If it were a rib, you'd feel it on forward bending also, I'd say.
Not sure if ultrasound can find this. Maybe you can have a quick call to some sport doctor - they have experience with torn muscles.
