Hi.
Such symptoms can be due to a generalized disorder like
Typhoid or so.
The pains and other symptoms you explained about your hands and feet can be a prodromal stage and since the body too heals such problems , every patient will get different sets of symptoms.
I would advise you the following:
You have to undergo a proper clinical examination to be done by a Doctor who can catch many of the problems on your proper history and physical examination and can then guide for further investigations and treatment.
Blood- complete blood picture,
kidney functions tests, blood sugar fasting and post-lunch,
Urine- routine,microscopy, culture and sensitivity ( before start of antibiotic)
Ultrasonography of abdomen., X-ray of the chest and so on.
The problem will be diagnosed and to get further treated as per the findings on the reports.
