I am a 25 year old female. For the past couple of weeks, my upper right eyelid twitches on and off and my lower left eyelid also twitches. The right eyelid twitches more though. my lower back has also been sore/tight for the past 3 weeks and I don't think I hurt it in any way. i have cut my coffee intake but have switched to tea and though my job can be kind of stressful, i've never experienced any symptoms like this before. And various parts of my body tingle and twitch too (upper leg or upper arm, cheek) and just small muscles, not like the entire leg or arm. I am not fatigued, but I also don't feel like 100%. I posted a couple weeks ago thinking these symptoms may be due to an STD since even my groin muscle twitches, but was told these other symptoms wouldn't be caused by an STD. Though I am still worried I may have an STD (had protected sex last April; going to see my OBGYN in March). Maybe these symptoms are caused by anxiety? I have also been bloated for the past few days and right after I eat I am uncomfortable and it doesn't even take much. Also I am getting red bumps that look like acne/bug bites on my neck which don't hurt at first but then become larger and painful with just a small whitehead and do eventually go away but after a week or so. I do have eczema but have treated for it and these bumps don't itch so I don't think it's eczema. I don't know if this is all caused by one thing or multiple things. anyone have any ideas?
