Undeserved DCI

On our last diving trip we (my wife and me) suffered from decompression sickness.
Both of us 2 star divers and each one of us hold about 170 dives (we used to dive almost every month about 6 to 9 dives each time).
We are healthy people (aged 26 and 25), not smoking, in good fitness and we kept drinking a lot between our dives.
We dive with compressed air (not Nitrox).
We are using Suunto=92s dive computer model : Solution Nitrox.
During our last trip we made 7 dives, we add our computer diving log.
Most of the dives I dive deeper than my wife (I wear the computer).
On our first day of diving we made three dives and we felt good after them.
On our second day of diving we made another two dives, after the second (and last) dive on this day I got a strange feeling (which I never felt before) of muscle pain in my hips and during that night I woke up in middle of it with a feeling of shiver at my legs (like thousand of ants walking beneath my legs skin).
As I woke in the third day morning I felt ok and we went dive again (two dives).
On the evening of that day we felt very tired and I started to feel scratching in my body And pain in my joints (hands and feet).
My wife felt pressure in her chest and general weakness.
On the next two days as these symptoms increased we went to hospital E.R and they sent us to Hyperberic chamber treatment with diagnosis of DCS type I.
After two days of treatments we felt much better.
Recently we passed Heart Eco sounder test with no signs of PFO.
We are writing you this mail cause maybe you can explain us what we made wrong, We became suspicious in our computer maybe it made some mistakes in time or depth calculations.
Can you suggest us how should we act for our next dives?

However our Medical Division wishes to let you know the following: The case described is clearly a DCS one with some neurological involvement, which should have been clasified a DCS Type II case according to the old classification system. The symptoms were already present, but were ignored and more dives were made. This may have contributed to the progression of the neuro-sensory symptoms. The successful treatment, although delayed, confirms the decompressive nature of the condition. DCS is a statistical phenomenon, and it is well known that it may affect a limited number of divers even after "normal dives" computed according to the standard decompression algorithms, such as the ones used by the currently available dive computers.
DAN is currently working at this problem and the first results of the 5 year research project Safe Dive, highlighted the algorithm parameters that deserve further attention and originated a revision of the algorithms which is currently being tested experimentally and on the field. More news are published on Alert Diver, DAN's Magazine, which is sent regularly to DAN Members worldwide. All divers are invited to participate in this project and to Join DAN in this task.
