roundworms??? benda 500mg?

Hello,
ok so my story is kinda long so ill try to keep it short as poss.. so I am 28 yrs old and for the past 11 years i have been addicted to prescription pain killers. now we all know what those can do to our digestive systems...well let me just say that i havent had a bm without some kind of help (laxative, enema, ect) in those 11 years. BTW i have been in a rehab program for 2 yrs now and am on suboxone which has the same constipating effect on me almost worse bc when i was abusing i would run out and get direhha from the withdraws and now i dont even do that.
so it has just been in the last year that i have started using enemas and suppositories mainly bc the lax pills have started making me throw up (i have been taking them for almost a decade and never had thrown up before!) when i do an enema or sup not much comes out. i have been worried for a long time that i have a compaction or lazy bowel or worse. my dr has prescribed me lactate i think it was called but i pay cash for the dr and just cant afford it!!
anyways for a while now every once in a while i will get the urge to have a bm on my own but by the time i get in the bathroom and try i cant get it out!!! so i have had to resort to using a helping finger if you know what i mean gross i know but gotta do what u gotta do. i did notice that there was a mucus around my extremely dry stool almost everytime (which of course due to constipation wasnt that often) but i never really thought that much about it. i hate to mention this bc i know i should have seen a dr about it a long time ago but i dont have insurance and for years i always assumed that my drug consumption had something to do with this (if you know a drug addict you know that if it thretens their high they wont do it) i have had at least a little blood im my stools for many years too. the mucus though i think i just noticed with in a year or so.
A couple days ago i got a new enema bag and i did about 2.5-3 qts just plain water. usually i just do the fleet pre-made ones. that night i expelled and nothing too much out of the ordinary but it was late at night and the water was pretty dark so i couldnt really see the solid stool that came out. the next day i had to go and it was soft and i sat on the toilet for a while after words bc it felt like there was more coming... when i saw what came out of me i knew i never ate anything that looked like that!! like most ppl i began looking at pics online. one of the first pics i came across was a pic of a roundworms nest in stool... it was exactally what came out of me!!!! also the pics of the transparent slimy worms looked like something i saw in it also. then i saw a pic of the stool covered in what i thought was mucus...they also say is rounds!!
i havent really noticed other symptoms not until i read what those were anyways lol... i have had more colds that just seemed to be respratory in the last year then any other time in my life!! with that said i havent had one in several months now which is the longest in a while.
ok so what i need to know is i ordered benda 500mg from amazon, has anyone had this brand of product?? was it affective? ordering meds out of the us scares me. but i cant afford all of the lab tests to maybe get a prescription. also i have read a million diff dosingings. just one for roundworms?? or 3 days of 100mg 2 times daily?? anyone know what is right if i am targeting rounds and not pins? alse if doing more enemas until my meds arive will it make more come out? will it piss them off and make them move more?
and i was wondering since i just noticed i have felt like something is tickeling around my colon!!! is this my mind or could this really be? if it happened before i may not have noticed....not sure. are they really strong enought to come out of our butts on their own like we have all seen in the pics???
any help or advise would be greatly appreciated!! im scared to death. i thought i was going to be sick all day the day i noticed but then i remembered reading that they can be thrown up!!! ugh! oh and let me tell you i have an irrational fear of reg earth worms!! i always have i dont even like to look at them so you could imagine what this is making me feel like!! thank you for reading i know its long and scatter brained Tweet
