Curcumin with Piperine and BPC 157, check your psoas muscles aren't causing this problem.
It can cause you issues with your shoulders and hips which can show up in knee pain as well.
While some supplements have shown to be helpful for some people, both in research and anecdotally, it's not a magic formula. Curcumin have some proven anti-inflammatory effects, but Piperine does not have evidence to support it in human trials, as far as I aware. With that, they can help as an addition. Ultimately your lifestyle and diet choices are more important.
Thank you for the detailed replies! Well, I have got an xray done on one of my shoulders and there are no bone spurs or anything similar so I don’t think that’s the problem.
Unfortunately, the doc was not able to pinpoint what cause the impingement in the first place but in my opinion it could have been the following:
1. I did not drink enough water these months, I am dehydrated.
2. I came back to working out after a back injury and I started training too heavy too quickly.
3. I have an anterior pelvic tilt and rounded shoulders. Perhaps my body has no balance and that’s what lead both shoulders to be impinged.
Please, let me know if any of these actually make any sense. I would love to combine the SARM stack with some corrective exercises to make sure I get rid of this problem completely, I just don’t know what the hell to do...
First to touch on the diet/supplement thing. Changing your diet around to a more anti-inflammatory one (I realise this is a very broad and often overused and misleading term) is important. Generally that means more healthy fats (advocado, virgin olive oil, wallnuts, eggs), more fish (there's really good evidence for DHA in especially salmon being anti-inflammatory) more
cruciferious vegetables, less refined sugar, alchohol i moderation and less starch (or keep it more towards brown rice, sweet potatoes and so on). There's also individual differences. For some people, moving away from beans (which are high in lectins that can cause inflammation for SOME) can help. Vegetables from the nightshade family like tomatoes and pebbers and some fruits (besides bananas) can trigger allergies in SOME as well, which can lead to greater systemic inflammation. Again, we differ as individuals. The core tenets are still worth following. Also, I personally like using tumeric (which is what curcumin is made from), garlic and cumin for cooking which all have anti-inflammatory properties.
Then comes the mental state. Relaxing, giving your brain rest, doing de-stressing activities and finding moments where you can unplug and unwind without having to think about anything is an undervalued tool. Physical and mental stress correlates with sympathetic activity of the nervous system, which in turn increases systemic inflammation in the body. Nevermind all the countless of other negative effects prolonged stress have on neurological, physiological and psychological health. Same with countless hours of screen time. So, use brain and body rest and relaxation as a tool.
Now, in regards to your physical activity, posture and your specific questions.
1. I don't know of any mechanism which being dehydrated would create prolonged impingement symptoms. Obviously it's important to be somewhat hydrated, but I don't think this should be attributed to your issue. Cramping would be another matter.
2. Yes, managing volume and load is KEY in any overuse pathology, which is what functional impingement is (you say the MRI shows no spurs). This is where you dial your training back, start with less weight, less reps and work your way back without pain. Do different exercises that do not hurt, and focus on form and technique. Feel free to post them here if you are doubtful about a certain technical issue and how that relates to your shoulder positioning and strain.
3. Yes, posture CAN have an effect on the joint translations/movements and peri-articular structures which can be overly stressed or irritated. An anterior tilt MIGHT play into that, but it might not. While on an individual basis working with posture can sometimes help improve biomechanics and in turn symptoms, at large there is no high quality evidence to suggest that a specific posture necessarily creates pain. With that, it's
always a good idea to have a good full body warmup, do quality dynamic and static stretching and to improve your muscle balance and function. Meaning in your case, do exercises that targets your posterior chain in various ways.
If I had you infront of me, saw you do what you do and could see what was going on, I could make something specific for you. As that is not possible, the above are general guidelines. If I was you, I would seek out a good muscoloskeletal physio that can help you out (some are better than others).
