I was doing rough housework and started feeling a word pressure on one spot in my back. ..as if someone s finger was pressing on my back. Days later, my back and right shoulder in the back got an excruciating pain, worse with some movements and burning feeling. At one point, my right arm and hand got numb and tingly. I ve been taking ibuprofen. That didn t work, so I ve taken Musflex, a pill each night for 2 nights. The pain is still there. What s causing it and what can i do?
