Leg cramps & Chemo

Hello Everyone, 

     I've had 12 weekly rounds of chemo since April (Carboplatin once every three weeks, and Paclitaxel every week).  I've lost my hair and recently gotten low blood counts, but the symptom that's plaguing me a bit is increased tightness in my calf and other leg muscles.   I have been able to take nice long walks in the morning before it gets hot, and I try to stretch before and after.  I feel like my legs are so tight each morning, that I think it's related to the chemo.  I'm trying to drink lots of water, and eat plenty of protein, but it's gotten progressively worse over the course of chemo.   

    Anyone experienced this and have some ideas that I can try out?

Thsnks so much
