Thank you for your answer.
I have uploaded a few photos to give you an idea about how inflamed the deltoid is. As you can see, the muscle is not very sore, and I experience pain only when I raise the arm. I feel the deltoid a bit tensed in the rest of the time.
I was not active in the gym before the IM, but I was after I had it. I experienced a bit of pain after I had the injection, but the muscle was not inflamed at that time. The last time I went to the gym I worked out my chest, and I kind of overburdened my deltoid. Two days later the muscle was very sore and painful. I could barely sleep. I took NSAIDs and applied an anti-inflammatory cream. Now it doesn't hurt as much as it did at the beginning, but it is still quite sore. My flexibility is very reduced.

Thank you.
It's possible for the sub-deltoid bursa of the shoulder to be affected by a vaccine that is placed too high in the deltoid. If the sub-deltoid bursa is inflamed, patients typically experience pain and discomfort with raising the arm, especially above shoulder level. The discomfort is usually characterized as "sharp" with the arm is raised and as a "dull ache" when the arm is at rest. If you were very active in the gym before this, it is possible that with decreased activity, you may began to fell deconditioned.
In general, for sub-deltoid bursitis, recommendations are for individuals to avoid activities overhead and to perform very light resistance rotator cuff strengthening
