Thank you for posting your query on HCM.
well it may be due to influenza
and pneumococcal vaccines
that you are taking . bodyaches , malaise , joint pains
, fatigue etc are common manifestations .
You can take a paracetamol
for this problem by asking your treating doctor . It generally subsides on its own without any treatment but still if it continues it needs evaluation as you were taking steroids .
If you have any further queries feel free to ask .
Hope it answers your query.
Take care .
