Achy Stiff Joints

I am 57 years old and was DX NSCLC in May, VATS in May with lower left lobe lobectomy. Staged 3a with 3 lymph nodes involved. Chemo - Cisplatin and Vinorelbine June - Aug, Rads Sept-October. Ok, so that takes care of the details.

I feel like every joint in my body aches now. I used to be able to get down on the floor to play with my grandchildren but these days it feels like I am an 80 year old woman. It hurts! I have had a bone scan and it came back clear.

Does anyone else have these symptoms? I am used to being active and think of myself as a young 57 year old. I am hoping this is something that will improve over time.
