NIH: Tendinitis

From wikipedia:

Tendonitis (also tenonitis or tendinitis) is an inflammation of a tendon. For example, patellar tendonitis (jumper's knee) is an inflammation of the patellar tendon, which connects the tibia to the patella.

Chronic overuse of tendons leads to microscopic tears within the collagen matrix, which gradually weakens the tissue. Swelling in a region of microdamage or partial tear can be detected visually or by palpation. Increased water content and disorganised collagen matrix in tendon lesions may be detected by ultrasonography or magnetic resonance imaging.

Due to their highly specialised ultrastructure and slow collagen turnover, tendons and ligaments are very slow to heal if injured, and rarely regain their original strength. Partial tears heal by the rapid production of disorganised type-III collagen, which is inferior in strength to normal tendon. Recurrence of injury in the damaged region of tendon is common.

Ahh, nice to be able to get a free three paragraphs with a block quote like that. So, why am I starting out with a description of tendinitis? Quite simple: it's a word that Nationals fans might have to get used to hearing for awhile. For example, the press release about Guzman yesterday reveals that to be John Patterson's diagnosis, and it's been reported in the WaPost that Majewski might have a touch of it as well. However, in Majewski's case, it looks to be more minor, and he did see some time on the mound in last night's victory over the Reds.

Patterson? Well...this morning Barry Svrulga is reporting in his Nationals Notebook that the May 18th return date might get pushed back two more weeks, with a new date of June 1 being eyed. That's an off day for the Nationals, though, who then head to Milwaukee the next day. The article isn't clear as to whether the 6/1 target would be for a rehab start, or to rejoin the big league club. Keep tuned for more updates on JPat, and to see which National gets tendinitis next.
