Anxiety can cause CS: Canker sores(CS) usually are not a sign of underlying illness. The cause of Aphthous Stomatitis(cancer sores) is incompletely understood but appears to involve some combination of genetics, stress, allergies, nutritional deficiencies and other factors. The mildly low WBC is likely unimportant and unrelated unless your absolute neutrophil count(ANC) is low, normal >1500. http://bit.ly/1hKZ4wy ...Read more

How can I insist on special tests, i.E. Blood tests, tests for food allergies?

How can I insist on special tests, i.E. Blood tests, tests for food allergies?

Offer to pay: Laboratory as well as radiological testing is one of the most expensive things we do in medicine. Insurance companies have contrived to reduce payments to physicians to amounts they paid 20-30 years ago. A medical opinion by a credentialed, board-certified specialist is a bargain. See an allergist. But if you must have that special test for your reassurance offer to pay for it out-of-pocket. ...Read more

I tested for all STD's via a wee test and blood tests. I had chlampyida and I was treated. Now have sores coming up down there, could it be herpes?

I tested for all STD's via a wee test and blood tests. I had chlampyida and I was treated. Now have sores coming up down there, could it be herpes?

Possibly yes: Herpes is the most common cause of painful sores "down there". But more detail needed. Exactly where are the sores (vaginal opening, labia, etc)? Also blisters? Tender swelling in groin? Partner with genital or oral herpes? Herpes diagnosis is easiest and treatment most effective when seen early, so check it out ASAP. Australia's sexual health centres are the world's best STD clinics; visit one. ...Read more

Reoccurring boils in armpits for years. Not from shaving, lots of blood tests including HIV all normal. Doctor hasn't given me an answer, what is it?

Hidradenitis: This could be hidradenitis suppurativa. If you see an Infectious Diseases doctor, probably they can confirm it for you. Often the triggers are stress or hormonal changes. Indeed, not all cases are caused by shaving. (recc clipping hair anyway over shaving). Hope you can get some improvement there. https://en.wikipedia.org/wiki/Hidradenitis_suppurativa ...Read more
