Last week I slept wrong and ended up with a huge knot in my shoulder.. After a week I had had enough so went to the Drs and she prescribed Voltaren Rapid. I took about 4 of the tablets but as they made me feel a little sick and my shoulder was a bit better I stopped

Now my shoulder is aching and tight again.. Is it ok to start the tablets again? I am also on Antibiotics for a sinus issue. (prescribed at the same time)
