i get those spasms and 'electric shocks' too. the shocks i get in my legs. i always end up scaring the ppl around me. its such a sudden and sharp uncomfortable feeling. sometimes painful that i would suddenly scream out. but its shortlived then im fine.
i get all those things you listed, different times, to different degrees as in sometimes worse than others. but then other times everything together, plus other painful uncomfortable experiences. make sure your docs do very thorough checks and rule out any other major concerns that are usually associated with lupus or develop because of lupus.
like Rob says, several things can come with it or because of it. ive already been diagnosed with some other conditions.
the time line for a flare im sure varies for everyone, it varies even for me. this last bout i had took me a month to be able to walk and move around again. but even now i still struggle with it.
but it can be a week, a couple of days. you will just need to recognise the signs of your flares. make sure the ppl closely around you know the signs too.
when i just got diagnosed, i had the facial rashes every month, not anymore. they've moved to every other part of my body. neck to toe tip. some break out are worse than others, where my skin hurts anywhere you touch me. and they look awful. and then when they are clearing up, i look like ive been physically beat up because of scars left behind. i looks kinda bruised.
anyways, im sure u'll be ok. try to maintain a good diet too. check you doc. everyone here will help you.
suffering from lupus, wish i were living with it, and surviving
