Hello
Thanks for writing to H.C.M. for your query.
I have gone through your query regarding inflamed tonsils, fever and pain over calf muscles not responding to analgesics.
After considering the all aspects of history of illness the possibilities of pain in calf may be due to -
(1) Myositis of calf muscles.
(2) Muscle cramps due to electrolyte imbalance.
(3) Pain of knee joint involving calf muscles as sometimes seen in rheumatic fever.
To confirm it you should go for these investigations-
(1) Blood- CPK-NAC, CBC, ESR, ASO titre.
Widal test.
(2) Urine - Routine and microscopic.
Protein in 24 hrs urine.
By this much work one can reach to correct diagnosis which can than be planed for treatment.

With Regards.

Hi Meetu,
Thanks for writing your query.

Pain in legs is common after high grade fever. This is known as myalgia.
It is due to some biochemical changes in the muscles as a result of high grade fever.

Pain will subside in due course of time(few days to weeks).
Give him proper rest. This will speed up the recovery.
He should be given nourishing diet to compensate loss of electrolytes due to fever.

Hot fomentation and local application of pain relieving gel will be helpful.
You can continue giving him pain killer for some relief from pain.

If the problem persists, get him examined by his Paeditrician.
I hope this is helpful to you.
Thanks.

Hi the doctor prescribe you right medicine. But pain in calf is not clear apply pain ointment, warm compress and ask if testes are also swollen. Then need change in medication. Do consult with physician. Take care.
