Welcome to HCM Forum,
I can understand what trouble u must be facing knowing that problem present but all reports shows nothing.
Its important to know tick bite
several years back doesn't have any aftereffects after few years - if anything it has it shows immediately.Having blood in urine and high WBC count
is totally different from this and could be due to urine tract infection so get it treated from nearest physician.
If all possible test shows nothing positive and still having tingling sensation
there and feeling of tick crawling underneath of skin with other symptoms of sleep disturbances,withdrawn behaviour could be sign of delusional disorder
So please visit along with your sons all test report to nearest psychiatrist
- he will definitely helps.
Hope this will help you.
