Hi @Sharon01
That sounds like the sort of thing you need to investigate with your oncologist. The other expert who may be helpful is a good pharmacist. Unfortunately, we are often not told enough about potential side effects-- I'm not sure if that is some patronising attitude designed to avoid frightening people or, even worse, an attempt to prevent some sort of mass hysteria where we talk ourselves into believing things are happening which are not. Not knowing what is happening is frightening when something we are not expecting crops up and is not helpful.
Muscle pain and horrible headaches are all too common during chemo but it's rare to be warned about it. The neulasta injections are also a potential culprit.
Chemo can do some diabolical things while (we hope) achieving its purpose of bumping off rogue cancer cells. Clexane is a bugger; I also developed a DVT during my first chemo. The gut jab (following a stint on Warfrin) just added insult to injury. Hang in there and nag until you get some sort of informed explanation. Mxx
