My brother-in-law's little girl was admitted to hospital erev Shabbos. Turns out she had been complaining for the past week about pain in her leg, and it wound up being a virus that is spreading in the frum community between children. The virus causes an infection in the leg that, if left untreated, can progress to the joints and cause irreparable damage.
B'H' they caught it in time, and she's now in hospital on IV as they try and rid the virus from her system. So if everyone could please daven for:
Shoshana Miriam bat Chana
And if any of you hear of a child complaining of pain in their leg, don't disregard it immediately as "just growing pains". It could be something else!
