Jason,
A recent study was published in the Journal or Science and Medicine in Sport, Vol 4 : 1, pp 104 - 115 entilted "Quadriceps Concentric and Eccentric Exercise 2: Differences in Muscle Strength, Fatige and EMG activity in Eccentrically exercised sore and Non Sore Muscles. In the discussion,the proposed causes of DOMS and how they might effect strength is explored. A reference is made to the chemical changes that occur within the muscle:
"..although they may well be associated with phagocytosis and cell necrosis, resulting in oedema and the accumulation of histamines...."
This was drawn from :
Armstrong, RB (1984). Mechanisms of exercise induced delayed onset muscular soreness: a brief review. Medicine and Science in Sports and Exercise. 23: 429-435.
I admit I have not read this study.

It sounds to me that the loads and speeds had to have been high level for it to produce statistically significant amounts of edema. I've recently submitted a review of multimode (different modes of exercise) for publication and I wasn't aware that there was a study linking swelling and eccentrics. The textbook that I referred to doesn't mention edema either (neither does the author whom I am colleagues with ). I use them everyday and haven't had complaints. Can you direct me to the research that you are talking about?

Eccentrics are popular modes of exercise for treatment of overuse syndromes and tendinitis. Eccentric exercise does produce DOMS (theoretically because they selectively recruit Type II fibers and small motor units) but after minimal bouts of exercise one gains DOMS immunity for about 6 weeks. The rationale for eccentrics is to replicate and concomitantly condition the tissue for the high tensile stresses it must undergo during functional activities. It can be implemented in the subacute phase, again when controlled for speed and load.

If one uses certain treatment suggestions for posterior shin splints on anterior shin splints, one can significantly worsen the situation, to the point of requiring surgery. And yes, I have seen it, and this poor lady can no longer walk without pain, and has permanent weakness.

Usually it occurs in the anterior compatment (Tib Ant, EHL, EDL, Peroneus Tertius), or deep posterior compartment (Tib Post, FHL, FDL). One suggestion of eccentrically training the dorsiflexors has the potential to seriously worsen an anterior compartment syndrome, because that is the problem in the first place - over use of the dorsiflexors eccentrically. It has been shown that increased muscular swelling occurs with eccentric exercise. By the way, I wouldn't be strapping this too tightly, and certainly not circumferentially, even with elasticised bandage. The compartment needs all the help it can get at this point.

Bone scan may help. A stress fracture is demonstrated by a very focal "hot spot", as opposed to a more diffuse lesion in periostitis.

Rest is effective - it is the easiest treatment suggestion of all - if it hurts don't do it. That doesn't fit my job description I'm afraid, I help people get back to doing things. Rest won't fix it either, it will only come back.
