Swelling after chemo

Hello Everyone, I am new to the forum I just completed 4 rounds of CarboPlatin and Taxotere on 5/21/09. Diagnosed triple negative 12/08. It is a 2nd diagnosis. 10 years ago I was diagnosed with stage IIB Breast cancer; 17 lymph nodes positive; 8 rounds of chemo and radiation, oh and I had a lumpectomy. so, 10 years later after routine mamogram a lump was found in same breast only triple negative. 10 years ago the tumor was er positive. Had double masectomy January with tisssue expanders. Has anyone experienced sever swelling in thighs after walking or standing? In the morning they go down a little, but swell again. The side of my thighs are also sore to the touch. Also have swelling in ankles and upper leg. Has anyone experinced this after? I did have weight gain due to fluid retention 10 years ago, but this feels different and how do I know the difference of blockage of veins or lymph system? Oops, maybe I shjould be asking the doctor that part. (callling in the a.m.) Thanks!
