Go and get it checked out.
Don’t wait or get fobbed off by your doctor.
I did something similar around 3 years ago (Sept 2013) – thought I should just MTFU and get on with it. Was still painful a few weeks later and went to see the Doc who said it was badly bruised and would take another few weeks to heal.
I got to Christmas and was in agony – went back to Doc who referred me to the Othopedic Triage unit – took 3 months for the appointment to come through. Had 6 weeks of physio which provided a slight improvement. Another 3 months later I was back at the Triage having a cortisone injection in my shoulder – all hunky dory for 6 months.
Woke up one morning in agony again – guess the injection had worn off – back to the Doc and waiting another 2 months to go back to Triage. Was offered more physio and another injection.
At this point I was about ready to smack the Doctor – I told them in no uncertain terms I wanted to see a specialist. In the previous 18 months I hadn’t had an xray or a scan and I was now convinced something wasn’t right (I’m a bit slow to catch on…).
8 weeks later I got an appointment with the Consultant shoulder specialist – who is a brilliant well regarded Orthopedic surgeon.
He sent me off for an xray (he was surprised I hadn’t had one too…).
Turns out I’d impacted my AC joint and with enough force for the bones to slide over each other and basically rough the ends up, oh and damaged a few other bits in the process.
The conversation turned to surgery – which he was basically going to cut 1/2 inch of my collar bone off and clean out the joint. Recovery time could be between 6 – 12 months.
Before this though I needed intense physio to get my should lined up properly as my shoulder blade was ‘winging’ and impinging the rotator joint and I was about a week away from a frozen shoulder.
I also had an ultra sound to check all the tendons were OK.
Before kicking off the 12 weeks of weekly physio I had 2 cortisone injections which hurt like hell (couldn’t lift my arm for 2 days) to alleviate the pain an swelling to help with the physio.
After the physio I went back to see Consultant and he was pretty pleased with the results but wanted to keep going with the physio and delayed surgery.
So another 3 months of physio ensued and another trip to the consultant.
He’s now delayed surgery indefinitely as the physio has realigned my shoulder correctly and opened up the AC joint to relieve the pressure on the meniscus.
It took me nearly 2 years to get sorted.
Don’t mess around go and get it checked.
