Hey guys I've haven't posted on here in a while been stressing alot been feeling so out of it, confused really bad memory problems i feel so sore every morning and feel like my lymph nodes are swollen not sure how to check. I've been to the emergency room mutiple times this week and they just keep saying Theve done tests in the past and there is no need to do anymore I'm not sure what to do I've seen so many doctors ive had mutiple mris, eegs, ekgs, blood tests, and many other tests all to no avail besides my vitamin d being low. Its killing me not knowing what's going on. Any advice would be appreciated thanks everyone! My sense of time feels so off like it just shoots past hours feel like minutes months like days. I feel so lost
