You've got great advice about
the lump, so I thought I'd chime in about
the health anxiety.
I get exactly like you feel when something unusual seems to be going on. I'll get frantic, feeling that I MUST see a doctor immediately, and unable to deal with possible waiting. It just feels like I'll go crazy from fear, or have to hide in bed until the appointment (not good to miss work), just in general that I CANNOT stand to wait.
Sometimes I can get a little control by talking with my husband or friends for consolation. Other times, a nap or good night's sleep (with help from Tylenol PM) makes me feel less freaked out the next day. None of these are sure-fire things for me; I basically just try anything that seems like it will help me to hang on a little bit longer. Just telling myself that it's not acting life-threatening is a help if the physical trigger isn't too bad. Distractions help, not so much in a big way, but that they decrease my baseline anxiety some, so that I'm not quite so near the edge from the extra HA.
Good luck to you. I hope you can find a way to hang on until you have answers.
