Hello, i have tons of chronic illness’s i will start of by saying that so when i was 18(currently 19, 20 next month) i was having constant irritation/tingling/weird sensation in my bladder that was causing me to miss all my courses my i attributed it my endometriosis and IBS, neuropathy. i went to the doc after about a month and had a negative uti test, about two weeks later same thing. i was dying from my regular pain but this pain but unbearable bc it was like inside it was like mentally messing with me and felt like i constantly had to go the bathroom. when k first gonsumtoms it was in nov in june i finally got tested for mycoplasma and ureaplasma and was positive for that and they gave me antibiotics and they worked for about two weeks then it came back. then i finally got a gyno that said it could possibly be a yeast infection bc i do get those when i take antibiotics so she gave me a pill for that that helped for a couple days. long story short she could figure it out, i was searching online and kinda had an idea of what i thought it was, i went to a urologist and he tried the same stuff, some new stuff none of it worked but he finally gave me the diagnosis i thought i had. it was interstitial cystitis. i encourage you to look into that. i get installations every week. for rat which is a hassle but worth it at this point. it is a debilitating disease that some people can never get under control and that is triggered by many different things but they can get it under control sometimes. but i have three that r debilitating so if u can get one under control i would look into it.
