Additional information: He went to urgent care and they did an X-ray and everything came back normal, as far as pulling something. He kind of maybe suspected that was a possibly the shot at that point. The diagnosis was a possible sprain. They sent him home with medications, anti-inflammatories and he took that but they barely worked. 2 days later, it was like nothing happened in the shoulder. When he took it, it kind of helped him a little bit and subsided some but, it was still quite painful. Every once in a while, it would spasm up, like catching a severe Charley horse in that thigh muscle. Sometimes it would last in a 5-to-10-minute stretch. Then, it would subside. It would normalize, then he would almost have to watch his movement. He had to sit still, then it would kind of subside. As soon as he got up to go to the bathroom, it would get irritated. At night, he had to watch how he would lay on it. He basically would have to lay on the left side most of the night. If it subsided, he could lie on the right side and it would feel like somebody just whaled on him and started punching him, it was that bad. He had not received any vaccination within 4 weeks. Treatment: They sent him home with anti-inflammatories that barely worked. It was Naproxen, like strong ibuprofen. It barely worked. When he took it, it kind of helped him a little bit and subsided some but, it was still quite painful. It was 500mg strength.

When he took it, it kind of helped him a little bit and subsided some but, it was still quite painful.  No follow-up attempts are possible. No further information is expected.
