First of all sorry, please lessen worrying/negative info since im already worry, hopeless about it also from reading. I need input on what test can i take to help find the culprit of my worsening unknowingly why. I was thinking if it might be strep throat/gut pathogen, etc. Im worried if this is or toxin attacking me. I already read some threads about infection and tests but i still cant understand it all. Since there are a lot of virus, bacterial and it seems the test is hard to get and uncommon since im in far away and the medical here isnt so advance (ordinary, common test). i cant also travel far. I know and feel helpless but since im so suffering i cant just do nothing about it. at least if theres anything i can do/try. The only option though is if the lab accept overseas client (shipping) though i still have to try hard to find doctor, clinic whos willing to help send. Shipping time is also a problem if it has to be <2days. Specialtylabs, doctorsdata, have partner here but some test from SL couldnt be done due to some factor. Also find out mayomedlab supposed to be partnered too but didnt due to some issue. I was hoping they will. Since 2 months ago my health gotten worse a lot. There are no changes from other thing as a culprit so its weird. Usually its pretty static with some ups and downs depends on my rest and diet. And usually it got better after i completely cut on food that im intolerance too, go on strict diet. but now i already did that but im still very terrible now and havent revert back to 3 months ago. My main/biggest problem since beginning was palpitation and tachycardia it has gotten terribly worse now but not only that some are also getting worse: chest tight abdominal tightness/air hunger, gas, jittery, stomach issue, muscle sore, sensitivity and unsure if insomnia different or not. Feels like when im still eating bad food and lack rest but i dont. The only suspicion/different thing happen i can find is dental and infection. #I got cough and sore throat 2months ago.last for more than 2 weeks took otc medicine and antibiotic. But no other symptoms. I thought it was only ordinary cough. I suspect could be common viral or gerd. After the cough it seems i was fine so i dont suspect anything. But then when i got worse after i thought it could mean something. #Theres also a helper who got skin rash on back of hand sometimes she help wash vegetable, massage. for couple of days, cause i didnt notice and she didnt tell. i dont get skin rash and i thought i cook it after n can only think positively though i was still worry. I dont know which come first the cough or her rash i guess my cough. But i dont know exactly hers. She also got flu its healed but i dont get flu. I know and worry it could mean something but she seems fine after it. I hope its not from it. #After that i got 4 dental filling+replacement work. Thats my first expectation of the culprit cause the timing is close but i dont seem to have a way out But theres also other possibility from infection.(virus, bacteria because of the cough and the helper case) I dont know what to do but i cant just do nothing Sorry for the hopelessness and patheticnes. I was hoping anyone could give input, idea also what test can i do. (Thats not so uncommon/hard for me to get to help at least) I was hesitant to even create this thread i also have lost hope of doctor but i still give effort and do so. Cause what other can i do. Thanks for whoever replying. Id be greatly appreciate any help. Good day to you all and happy new year.
