52 degrees! Are you kidding me???! Kay, you're gonna love the Caribbean and Florida. Right now the water temp is 87 degrees....really. Glad you enjoyed your dives. Regards, Larry Stein

My apologies Kay, The last few responses have essentially hijacked your thread and your questions. I think that Drew's responses were thoughtful and reasonable. Recommendations regarding diving and asthma are changing. Under the right conditions you can successfully and safely dive but...

Steve, I have watched this thread and the one on O2 administration through a demand valve. You seem to want to stick to good science and proper procedure. Then you talk out of the other side of your....mouth. Let's make this easy. YOU'RE the DOCTOR and this patient is your....SON...

There are rules concerning the size and number of fish you can catch and the types of fish you can catch. These are posted by the State of Florida Department of Natural Resources and the Florida Marine Patrol. The size of the fish you are permitted to take may change and you should update you...

Hi Stephen, First, eating barracuda...it can be done and they can be tasty BUT it is not recommended because they can have ciguatera toxin. This is nasty and best left alone. As a kid, I used to eat small ones. Once the fish is dead, it very quickly picks up an odd metallic smell. Now...

As Suemermaid said, you get your Sea Legs. This is the term used to indicate that you have become accustomed to the motions that may lead to motion sickness. I don't know if others have experienced this but there is a kind of "reverse sea legs". Following several days on small boats or...

Hi Amber, There are several ways your dental work could affect your diving. If you had a "simple" extraction (vs. surgical extraction), you should wait about a week to ten days before diving again. You must be off all precription pain medication...ie. narcotics. You must be able to hold...

Cen_Fla_Keith, OK. Here goes again. The stories are true but the incidence is very low...rare even. Exploding teeth and crowns are even more rare. The most likely cause of tooth pain during diving is a sinus squeeze. The pain can refer to the upper molar teeth and can feel exactly...

bfd_dan, There are really two different "problems" here and the answers are different. First, there are many causes of anemia...blood loss, iron deficiency, leukemia to name a few. Identify the problem and solve it if possible. Whe the anemia is gone, you can dive safely. If you cannot...

Hi sea nfm, I can tell you exactly why your buddy couldn't secure your tank. First, a little work of explanation. One of my buddies uses "fat" Genesis tanks with a particular BC that has a strap that isn't quite long enough to secure them properly...the cam comes down near the end of the...

DrBill, I'm inclined to agree with padiscubapro. A cracked tank valve is exactly what led to a personal rescue about 10 years ago. I had to rescue an experienced divemaster from 8O feet. He rushed up to me with the two biggest eyes I've ever seen. Then he removed my second stage after...

gert7to3, Sincerest apologies, I didn't think it possible to have dental anesthesia and do a dive in the same day...looks like I was wrong. Laurence Stein DDS

David, I don't think it is a good idea to dive the same day as the dental procedure. In fact, recommendations for diving following dental procedures often say that a week is appropriate. Certainly, if it is a simple filling, no numbness, no problem. Surgery, root canals, periodontal...

Hi David, No, you cannot dive during the dental procedure! :11:. Something simple may only require a bonded filling. An exposed nerve or a devitalized nerve is going to need a root canal, post and a crown. A fractured root could require an extraction. A head injury could require....never...

Gert7to3, Methinks we are getting a little ahead of ourselves...this guy is having local anesthetic to numb a tooth. He's not having a stroke. It's gonna go away the same day. I really don't think diving with a numb lip is an issue, do you? Ability to hold a reg is only an issue during...

Hi MO Diver, Well, either Saturation is going to correct me or correct you... To my knowledge, cones are associated with color vision rather than hearing. Donno...could be wrong...unless you are into that old LDS and sounds appear as colors. Maybe it's a symptom of ciguatera...

Hi Corrado, Your symptoms suggest an injury to the inner ear. You did multiple dives and had no other symptoms to suggest worsening DCS. Did you experience any difficulty clearing during the dive(s), pain on ascent or descent, vertigo during or immediately following a particular dive? As...

Hi nemisis77, Take it easy. I would tend to agree with Saturation and in addition would suggest that you might have experienced alternobaric vertigo. This is created by unequal pressure within both of you middle ears. This inequality is confusing to the brain and may result in dizziness...

Hi mtnredhed, Sorry, I was away. It sounds like a sinus squeeze...especially if there are no dental problems. Upper molar pain referral is typical and depending on the length of exposure, it may clear immediately or slowly over a few hours. I have typically seen this type of squeeze in...

The latest report in the Miami Herald said neither diver was certified. Their dive experience was 3 dives and the 14 year old was dead due to drowning with air remaining in his tank. I too used to free dive with my father. We would spearfish and we would go to the Cayman Islands before it...
