Hi @lgray3911 The creepy electric pain is usually nerve damage. It's horrible but generally passes. Eventually. Its also possible that you are having some feedback from your pain meds, which can make you tetchy. Lyrica can help with the nerve pain and can also have a sedative effect--I only ever take it at night as I can tolerate the feeling of critters crawling up and down my arm when the lights are on (I can see they don't exist then)
Heading into chemo is enough to do any ones' head in. Put it on top of everything else and it's surprising there are not more of us running down the road screaming our heads off. You may want to think about some sleeping pills as you will probably be taking some steroids for a few days with your chemo. Instant roid rage for some of us. Sleep is the thing we all crave, I hope you get some in the next few days. Marg
