Hi, I had gone through your question and understand your concerns. You should be worried but not too much. With such presentations in my clinic, I would first rule out serious conditions as
Reactive arthritis with Ig M,G to Chlamydia trachomatis(Reiter's syndrome), associated with gastrointestinal infections(Salmonella, Shigella or Campylobacter), for this you should give stool culture; dysmetabolic arthritis(check uric acid), growing pain and osteoporosis(Calcium, Vit D,
glucosamine,chondroitin sulfate),rheumatoid arthritis(
rheumatoid factor,
C-reactive protein),circulating antibodies to exclude autoimmune process,Antistreptolysin-O to exclude
rheumatism .
I suggest
-take a rest in the bed, do not jump;
-massage with Diclofenac gel, bandage;
-ibuprofen for 10-14 days;
-cefixime 4 mg/kg/dose twice a day for 5 days;
-vizylac 1 capsule daily for normal flora.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing your baby good health.
