PG,
I think your HA is sending up red flags here.
Remember the old medical adage about
hearing hoof beats...(think horses, not zebras!)
Random aches and pains are pretty common, and usually benign, not a sign of something catastrophic, like our anxiety tries to tell us.
Especially in light of the good results from your medical tests...you can trust your doctor's reassurance on this.
Keep working on the HA self help/CBT material you have...or see our Resources for links.
It is an ongoing process...I know, I am still a work in progress too!
With encouragement,
S.C.
