the symptoms you have may or may not be related to a sexually transmitted disease. even if it were, there are tons of other STDs that can cause those kind of symptoms
the only way to tell for sure is get tested
yung sinasabi mong parang lymph node sa likod ng tenga, thats nothing to be afraid of, its very common and most of the time wala namang problema yan. kahit ako merong maliit na parang bukol sa likod ng tenga ko na parang pimple pero hindi naman pimple, sobrang tagal na nito hindi ko na nga matandaan kung kelan nagsimula. pag pinilit kong putukin dudugo siya then after a few days balik ulit sa ganun
yung ubo mo naman, that could be caused by lots of viruses, especially sa panahon ngayon na init, ulan, init, ulan. usong uso ang mga cold-like viruses
eto sample. dati ako inuubo tapos lagnat pag gabi pero umaga walang lagnat. if you look at the symptoms kala mo its already pneumonia, pero pag punta ko sa doctor, its not pneumonia but just some viral infection. binigyan lang ako ng corresponding anti-biotics
yung depression mo naman, its obvious its psychological. if you think (or rather if your mind believes) you have a certain disease, you will start to feel the symptoms of that disease. may medical term to nakalimutan ko lang.
