I found some information from web-site, hope it's usefual for you. but most important, you need to follow doctor's instruction or consult more doctors to define the disease:
I knew 1 bk mama who's bb was suffered from this illness few mos ago. Seems until now he still need to have the follow-up by the Govt Hospital & need to take the medicine.
She went to the private Hospital first as her son had high fever ....... . Her case was : When the Dr. in pr. Hospital think the bb is this case, they refer them to the Gov't hospital & the bb had the treatment there .
If your Dr. have this query, why he don't refer you to the Govt Hospital for a futher check up? This illness is also troublesome wow~ & better have it to be treat asap!
Hope he will be fine soon!
