hello doctor,my mom is 60 years old. last november she fell sick, had fever up to 101-102 degrees C for 15-20 days where no specific diagnosis could be made by the doctors through blood test (changed 2 doctors). Since then she has fallen sick and weak. she is not having energy as she used to have before and she is feeling weak all the time. IN February, she took Polybion tablets, one tablet a day for 5 days. On day 3 she developed skin eruptions like mosquito bites ( rash ) on both her hands which did not subside till date, i.e. March 1, 2013. for the weakness, she is still weak. her thyroid and blood sugar has been checked and they were normal. is this rash and weakness because of polybion or not. please suggest what can be done for her weakness and rash.
