Hi, my son just called me from college (at 12:30 am) to say he has acute lower back pain that just started all of a sudden this evening. He has taken Advil but is in a lot of pain. He asked me what to suspect, he has had no injury or fall that he can remember. (I know he's was wondering if Meningitus (sp) or something starts this way). I know he is concerned because he called me at this late hour. He and I are stumped. He is a senior, age 22 and is not an alarmist. He has asthma and has always been very self aware and sensible regarding health issues. I am worried. Sorry I am going to have to check more before I use you, don't know how to evaluate the safety of your website before I give a credit card number. Hope your legit.
