Hi thanks for using HCM.
Since you hav tired, losing voice due to swelling and painful swelling growing faster with raised CRP level, these suggest may be due to infection and the lumps may be lymphnode. But to take precaution since complete hemogram is normal get examined by an ENT specialist
and if infection you have to do salt water gargle, take antibiotic and antiinlamatory drugs, If its not due to infection I prefer you to take one CT scan
. Wish you good health.
