Hi DUSHOUTH,
Now before I tell you what I would do I totally agree with the comment from
CarterSUPPhysio, in that you should run everything past your therapist first, before actioning any advice from a board post like mine. however.
I have had a heap of shoulder injuries over the years and subsequent surgery.
Regardless, I still occasionally sustain rotator cuff injuries (on my non-operated shoulder).
When this happens, this is what I do to treat it fast:
I totally fatigue the shoulder as many times as I can in a day with VERY light band work (theraband exercises).
I also ice the shoulder every evening - bag of peas etc.
There are two main exercises I would recommend you consider doing (they are simple yet very effective) you can see them in the video below, and make sure the band you use is VERY light and easy, however do every set till failure/fatigue.
Naturally run these past the physio first to ensure the injury will benefit. Mine always responds very well. Further to this with a light band you can literally have one at home, at work etc, so it multiple times per day.
Link to exercises below:
I suggest you do the above band work for the weeks leading up to trip.
Approximately 3-4 days before the trip I I'd get some Voltaren Anti-Inflammatory tablets into your system.
I recommend you buy the
Voltaren Rapid 25mg tabs over the counter at chemist (you do not need a prescription) and if I was you I would take one in the morning and one in the evening with food. After 2 days of taking them any remaining pain levels should come down and you will be fine for your trip. That said, when overseas I would keep taking them until your last day.
When taking anti-inflammatory tabs the key is to not over do it, do not prolong the use, and use them at the right time, to get you through the pain period you need to get through. Another very important point is to ensure you take each tab with food i.e. not on an empty stomach.
I did a lot of competitive weightlifting when I was younger and I am now looking to enter a few masters (over 45's) bench press comps so when it comes to shoulder injuries I've got some pretty good experience.
Anyway I hope this helps.
All the best mate.
