Hi @Trikki2 I am in the same position. Eleven days post mastectomy and lymph clearance. Extremely sore and swollen. Home nurse sent me to their doctor who pronounced everything normal. They are interested if it is like a balloon but smallish swellings don't seem to excite them. However, if in doubt, get it checked out. It would be nice if we knew this stuff in advance wouldn't it! Get those pain killers out even if you don't want to. Hugs, cause we need it!
