Hello Ashley :
DCS Reoccurrence
No, DCS symptoms cannot reappear [if you are not changing pressure] if it is a joint pain (“bends”

problem. If it were neurological DCS, then it would probably best be described as persistence rather than reappearance.
Once a gas phase has dissolved, it is gone and the body has no “memory” of it. If someone has a DCS problem that goes untreated for hours, other effects , such as edema, can result.
Delayed DCS from Multiple Dives
This is definitely known [references below]. Therefore, you could definitely have been in trouble zones during the day and not known it. This would not persist for weeks later, however. If you were treated in one of chambers on the Caymans, and the “bubble problem: was not cured, you would have experienced [probably] something on the plane flight home.
You might be a “sensitive” with regard to bubble formation. There is variability amongst individuals. This was commented upon by JS Haldane in his 1905 paper on “compressed air sickness” and his new decompression tables. The proclivity is sometimes used by groups to test a table (the “miners’ canary”

. [In another lab with which I was associated, conversely, they never asked a "bent" test subject to return.]
DCS?
If you had shortness of breath following diving, this looks like the “chokes.” It is a very serious form of DCS. In the old days, if you got a whiff of cigarette smoke, you would have experienced fits of coughing (Behnke’s sign) if this was the problem. It is also possible that "shotness of breath" was peripheral to your diving. Check with a physician.
Return of Problems
Standing in the cold will not provoke DCS problems weeks post dive. That said, muscle soreness and rash should be checked into by a physician. As the others posted, this could be sign of other problems. You were right to inquire about your DCS on this FORUM. Take note that people have muscle soreness and rash and have never been diving- could be a problem.
