Bone/muscle pain from Herceptin?

[Jane]

hi folks - a question about significant muscle/joint pain while on Herceptin... i'm a 47-year-old Stage 3 breast cancer patient - her2 3+, 6/15 lymph nodes positive, bilateral mastectomy in April 05. Have done 6 months of chemo (finished Oct. 21st) and am now into 6 weeks of daily radiation. I've withstood the chemo amazingly well (thank God).

I've been getting Herceptin weekly since August '05 and am now having pretty significant bone/joint pain. It feels like i've laid in bed for months and am walking/moving for the first time. (That's not the case at all as I have remained very active through all my treatments.)

Examples: I wake up every morning with pretty strong pain just laying in bed....when i sit down and go to get up, it hurts.........when my young kids sit on my lap, my upper thighs hurt. I can't distinguish if it's bone or muscle pain that I'm feeling.

Do any of you experience this? At first I thought it was from 6 mos. of chemo and my body finally rebelling. But now i'm kind of worrying.

thanks for any experiences and help you can give me.

this site is wonderful -

regards,
jane
