@twiggyjumps yes, I got all sorts of weird pains and odd feelings.
Sometimes the pains would start in one place in the morning and move around my head and neck area during the day, under my right ear and jaw was the main starting place.
Part of it I put down to having only had the port a cath inserted a week before starting, so it felt strange too. I thought I could feel it in my neck and running down the middle of my chest, when I swallowed.
I had a thumping heart too ( interesting to hear it was the Dex, no one told me that)
I had strange pains in the neck, chest and upper back, and screaming pain in the jaw one night that never happened again.
Very itchy eyes for the first two infusions that are now really weepy, especially in the mornings.
I suddenly started waking up with very sore patches under both arms on the sides of both breasts, massaging helped. I had both breasts reduced ( and lumpectomy) two months before starting chemo, but they were quite well healed and hadn't been a problem recently. Some mornings they are fine, some they are really sore.
Oh, and lumps in the throat too especially with the first infusion, not nearly as bad with the second two.
Mouth feels like a cats tongue, all rough and sandpapery, not sore though.
So yes, weird side effects.
I ran all of them past my Oncologist, some he had an answer for, some he looked puzzled and shook his head, he had no idea about them.
I must say they were worst the first time, each dose after was much better, just the expected side effects like constipation and nausea, not the really strange pains.
