welcome to health care magic,
this is most common complain observed after chicken gunia,it remains for pretty long time,that one has to bear it.
for relief of pain you may take diclofenac
tablet or injection,avoid as far as possible,as long time use it may produce peptic ulcer
or hyper acidity,
if at a time one joint is affected,you may apply diclfenac gel,instead of tablet.
it is time taking process,gradually it will be subsided.
