(The background is written in past tense, but I still have the pain though)
I am an individual who has had ligament laxity all my life. I was the kid who could place their thumb completely flat on their arm. I have noticed since I was a child that my sternoclavicular joints (SCJ) have been unstable and seemed strange. They had never caused me any trouble until a year ago. I started to go to the gym two years ago and found that I would commonly get sternum and shoulder pain. The pain wasn’t permanent, and would go away after a few days. Over time though, the pain would linger longer and longer. Things that hurt my sternum the most were dips. My left shoulder hurt with any dumbell/barbell row, OHP etc. Come January of 2019, I was doing one arm hangs with my right arm were I felt a tearing sensation in a specific spot in my sternum, where the 2nd rib on the right connects to the sternum. The pain never went away. Around this time, my left shoulder also gave in, and the pain also became chronic after a session of doing dumbell rows. This was the file nail in the coffin.
I now had chronic pain in my sternum(called Costochindritis) and shoulder. No physios, chiropractors, muscle manipulators, masseurs, chinese medicine practitioners could help me. Ultrasound of my left shoulder came back clear. X-rays of my spine, chest, left shoulder came back clear. The pain in my sternum lingered, and would get worse if I slightly physically exerted myself. The pain in my shoulder would radiate down my arm into my fingers. I no longer was going to the gym and I felt as if I was withering away.
I dealt with the pain for a year with no clue of the reason, until one day I suspected it was due to my SCJ. I did some research, and I discovered that an unstable SCJ can cause sternum and shoulder pain! This was a breakthrough for me, and I began to read studies and articles. Surgery for the SCJ seemed to be the most common treatment but has a fairly high fatality rate due to the proximity of the vascularity of the neck. Another treatment rarely mentioned was Prolotherapy. My understanding of Prolotherapy is that it is an injection therapy involving using an irritant such as Dextrose solution or Sodium Morrhuate to cause a localised inflammatory response at the entheses of connective tissues such as tendons and ligaments. The irritant is usually refered to as a proliferant. Prolotherapy is commonly used to treat ligament laxity, which is exactly what I had.
I took a video of my Sternoclavicular joint instability, you can PM me for the video. This link is a album of snippets of the video.

I am going to write posts on my experience with prolotherapy. I am going to do the injections myself in my sternum, SCJ and potentially shoulder if I can reach the injection sites. I will be using a 25% Dextrose solution made from 50% dextrose with 0.9% Saline. I will do this by taking 10ml of 50% dextrose and 10ml of Saline. The solution must be hypertonic, this is why saline is being used instead of sterile water so that the solution stays hypertonic. I will then inject 1-2cc into each site using a “peppering fashion” by stabbing the ligaments by moving the needle up and down before injecting the proliferant. I will do many injections in the same area. I will be using a 25G needle for the injections and might use a 23G for the shoulder as I will have to go deeper. Lidocaine will not be used in the solution as it has been found to be toxic to cells; I may only apply it on the skin if needed due to any pain.
