Hello good morning. Sir/ madam. Since these many days suffering from vitamin d and b12 deficiency as well as other some autoimmune disorders, after having test like vitamin d deficiency test and liver function test which were screened deficient including increased sgot in liver function test. Therefore after getting regular sunshine and diet my bone pain is in a bit of control accept joints both arms and legs feeling weaken, no improvement in weight gain, often getting flu, cold and fever (which is uncertain sometimes in morning or evening) and whenever getting a bath it's becoming more problematic, and within these all mt doctor had suggest for the some other tests like ncv upper limbs test and hib test but both tests were resulted fair. Specially I was worried about hib but it was shown - not reactive. And according to one of previous test for widal it was reported that I had been suffering from typhoid. So my query is here about the fever and flu which I am developing frequently is it because of typhoid or something else for that I am getting it again and again. Bcoz currently the doctor I visited he said there's no any issue regarding typhoid. And has prescribed me as follows the medicines. 1.veloz d capsules. 2.lonazep 0.5 m. 3.pentanerv nt. 4.ensure hp powder. Please correlate with this queries medically. Thanks.
