Last weekend my daughter's went to spend time with their Grandma for her birthday weekend since they knew they had school on Monday,"my mom's", "their Grandma's" actual birthday. Anyhow, they both had a cold, and a cough, but they said they felt good enough to still go. Well My mom lives in Stockton, and she barely moved in and along with the house, they have a pool over looking the Pacific Ocean. Beautiful! Well my girls had asked me if they could go swimming, and I told them "Well, judge the weather on that, if it is too cold then no, etc. Well they said it was a real hot day so they went ahead and went swimming. Well after they were done my oldest the 17 year old had stated that it was freezing water, but they end up getting knumb after awhile, and the next day they woke up fine. I was kind of upset that they went swimming being sick, but they seem to be ok, so I brushed it off. Well now my 17 year old is complaining about her right side on her back hurts, wear she cant seem to get in a comfortable position, and when she takes a breathe it feels very uncomfortable. The question I have in re: to this: " Could it be she had gotten herself pnemonia? Please advise.
