@leslieb52 Hi my Prolia twin! Promised an update of my drip to dermatologist. Nothing much to report only that she's taken a biopsy but I won't have results until 3 Feb as I'm going away next week for 8 days so will get results when I see her again. However, she thinks it may be an autoimune rash which who knows what could have triggered it. Hopefully nothing more serious! I'm still thinking the Prolia's caused it as it's a known side effect whether autoimune or otherwise (I don't really know what autoimune means other than it's the body recognising something strange has been put in there! I'll be disappointed if it is the Prolia as I would think if it is I'll need to change to a bisphosphinate (sorry about my spelling). If the biopsy shows autoimune then from there I'll need a blood test which hopefully will show what is causing it. Hope everyone who reads this are all well.
