Kathy: The numbness or tingling that you are describing sounds like neuropathy. I have had it since I was on chemo. My onco is very careful not to let it get to bad. There are meds that you can take to help reverse these symptoms. Now to the swelling. Don't mess around. You really need to get checked asap. That only happened to me once while on chemo. I called my onco and she sent me to the nearest ER for an ultrasound just to make sure that there were no blood clots. You might want to elevate your feet (maybe a little footstool) while at work. The aches in your thighs and legs are probably a side effect from the chemo. Hot, hot baths!
Please go to the ER tomorrow.
