Hello, Last week I slept on a futon at a friend s house. The next day I discovered a knot in my left shoulder. The knot is about the size of a golf ball and inhibited me from full range motion in my shoulder. I noticed my shoulder seemed pushed further forward than usual. During stretching I noticed the knot was not only below my clavicle as well as I had another knot under my arm pit. Since stretching I m experiencing pulling and spasms.
Hello, The symptoms seem to be related to a pulled muscle. I suggest using muscle relaxant such as Baclofen. I also suggest using Voltaren gel for local application.  Furthermore, I recommend gentle stretching.  Hope I have answered your query. Let me know if I can assist you further.  Chat Doctor.
