Thanks Jan. I feel anxious about calling my pdoc for an earlier appointment as I am worried this will pass and I will look like I am making a fuss out of nothing. I might see if it worsens over the weekend. I don't know, maybe I am being silly. It is difficult to think straight at the moment. I just went for a walk on the beach and that helped a little. Back to more study. Thanks again. I will keep considering calling my pdoc.
