Cervical and neck pain

hi!

Just finished my rads (28) and feeling tired. But a new pain appeared : cervical pain. Never got it before.

It makes me anxious so anxious. Im on herceptin may be it is the reason.

waking up like an old lady, feeling dizzy but no balance problem. Im doing my exercices on my toes and yoga without problem. But my neck hurts and especially cervical.

I talked about it to my onc she said it was taxotere or rads. My tumor markers are low, my surgery was good, I do have good post op surgery Biopsy results ... she said I should be patient but I imagine everything and the Worst.

Does anyone experience such pain? Thank you very much for your help !
