Hi Sharmur and welcome. I, too, cannot stand reading 'unremarkable' - ugh!
It sounds like your rhematologist was getting a full blood panel to help rule out any other infections/issues that may be causing your issues.
I am not familiar enough with some of your issues/questions to give you any answers, but I wanted to welcome you to HW until someone can hopefully give you some better thoughts.
I do want to ask - how long have you been on elavil and did any of these issues start AFTER taking it? Elavil is an interesting drug, but it can do some funky things to you. You might want to check online to see a more in-depth look at side-effects. What other meds other than vicodin have you been taking?
