Brenda,
What chemo are you getting? After my 3rd treatment of Cytoxin/Taxotere, I developed a whelp type rash that seemed to travel all over my body and itched, especially my feet and hands. I tried benadryl and nothing worked. I called my oncs office and she prescribed prednisone dose pack and almost immediately it got better and was gone within a few days. I expected the same reaction after the 4th treatment, but it never happened.
Gaining weight is quite common with chemo. I was surprised as I thought all lose weight. It's probably the premeds and the steroids (decadron) attributing to much of the weight gain.
Your oncs office should have an on-call nurse 24 hours a day. I would always give them a call if something didn't seem right. Many times they'll give you a few suggestions to try or notify the onc who will be able to prescribe something to help the side effects.
