Thank you for posting your query on HCM.
Well it may be due to either fibromyalgias or flu
but at present whatever history you have told it seems to be due to flu only . Flu leads to sweating bodyache , malaise
, joint pains
etc. which may last long even when theflu is over . A simple paracetamol
will suffice for these symptoms .
Hope it answers your query.
Take care .
