Please help me find the source of nightmare shoulder/chest injury

Hi guys i really hope someone can help - im nearly 2yrs suffering from this prob that no speciliasts can pin down....

Over 18 months ago my shoulder got really sore after kettlebells lifting and some flys
since then i have tried it all to no help;
osteo
sports physio
accupuncture
Pain killers and anti inflams
athoroscopy
rest
i have had endless scans all come back clear. It has no common symptoms of anything else such as fotator cuff.
It feels like impingement but i have no tingling in hands or fingers.

I had a bone scan and it revealed i have inflammation of ribs 1,4 and 5.
The only thing that sorkd was jn the summer my slecialist gave me the steriod predisalone. I only took it for 4 weeks and kept training thro injury. It totally went away during those 4 weeks it was like a miracle. I could do all weights in gym. But then one night out of nowhere the pain came back (pec minor area) and hasnt gone away since.


. Ive Tried strong diclofenac 75mg twice a day. 2 weeks in and hasnt touched the sides. So im now back to 20mg Predisone for 4 weeks but a week in and no difference. Im gutted and getting very frustrated no one knows whats up or how to help!
(the only other thing i can loosely think is i switched from fags to e-ecigs just before this started but im kind of ruling that out as the pain totaly went away during the predisalone

When i first got the injury i thought it was either a rotator cuff or pec minor injury. I took off 8 weeks. Didnt get better so went down the osteopath route for around 6months - he tried everything including deep tissue massage, stretching accupunture, rock tape etc.

Tried working around the injury in the gym, tried more time off. Nothing improved it.

Had multiple mri and bone scans. Nothing was injured. But the bone scan revealed inflammation on ribs 1, 4 and 5. The inflammation is on the small bit that connects the rib to the centre of rib cage. It feels like impingement as it takes your breath away but i guess thats the ribs inflammed.

Over 18months on and only 4wks predisone took pain away. After finishing it one night severe pain came back out of nowhere in same place - that was 2months ago. Since then ive tried to train thro the pain

I then got a course of super strong anti inflammatories - diclofenac 150mg a day - again did nothing

So on monday i started another 4wks predisone. Im so fed up and frustrated.

I managed to gain 10lbs bulking over the last 2 months and seen fairly decent growth but working thro the injury just keeps flaring up. Im taking this whole week off while i take the predisone. .

All the specialsts are at a loss and my bupa allowance is maxxed out.

Someone mentioned maybe a long thoracic nerve injury? But wouldnt that have shown on an the mri, ct and/or bone scan ive had done?

It really feels like a nerve or impingement bit i dont have tingling or numb hands.

Hope someome may have some ideas.... Thanks

Just tried a few stability movements with a theraband...


External rotation is Painful/burning
External rotation with arm abduction 90degrees is painful/burning
Internal rotation is fine no pain
Abduction is fine no painp


Does this help diagnose any further?
