This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
That is due to the inflammation in the body from recent infection.
The body's immune system can go overdrive attacking its own tissues.
This can last for several weeks also known as reactive arthritis.
Oral steroid course with prednisone 40 mg daily for 5 days then tapered to 10 mg daily for 2-3 weeks should help with the symptoms.
Tiredness is also part of this.
Other causes of tiredness can be hypothyroidism or thyroid gland disorder, diabetes, iron deficiency.
Please discuss with your doctor soon.
It was my pleasure to help you today.
