First of all a very warm welcome to HCM,
Just went through your problem and i picked it up immediately to answer it. Now please go through what i have to say with a little extra concentration. Your Weight loss
is so so ....but I am more concerned about your "Headache" with associated fever
& chill -
From the history you provided, i think that you should immediately -
(1) take an antibiotics coverage
(2) Oral gurgle based on "povidone
(Drugs not written as not allowed by HCM)
Also, do -
(a) Throat Swab culture and sensitivity
(b) PBS for MP
(c) R/E Blood
Mind it that any antibiotic coverage is based on sensitivity report.
So, immediate consultation with your local doctor is recommended.
Please maintain your nutrition and hydration, its very very important.
Wish, i could help you more but here from HCM, i sincerely wish you a very very early recovery.
