Nerve pain came back

Kinda all of a sudden, the nerve pain down my right arm and triceps came back.  Not as bad as when I first had it but close.  Maybe pain in month 3 or so.  Had been having mild dull pain in hand and arm, more like overworked soreness so didn't think much about it.  Was feeling a little crummy on Sunday but still went to work Woodland.  Towards the end of shift I started feeling bad.  Had to lie down a few times. Was hoping to lie down after i got home but ended up making dinner and stayed up. Feeling a littler worser at night.  Next day, drive to Redlands.  Driving hurt.  Had Sage drive home from Banning.  Was hard to sleep and getting up hurt a lot. Working at computer at work brought on the same pain.  Had just seen Chip on Thursday but got myself back in on Wednesday.  He says there's some swelling.  But I can't recall doing anything out of ordinary. Cracked a few things. Then he says he's going to put me on this list for an ultrasound.  Good, maybe  I can not get those MRIs Deborah wanted me to get. $1500 for 3 tests. That's a lot. So the appointment was made for tomorrow.  Sounds like a Nerve Test instead of an ultrasound, but will test if I have nerve damage.   Best thing, I think it won't cost me anything.
