I came down with a severe calf pain, which made walking difficult,
last Sunday.  Onset was very sudden.

Tuesday eve, I noticed swelling in the calf including the ankles so I
called my HMO 24 hr nurse.  To my suprise she told me to go to the ER
immediatley.  At the ER, I recieved an ultrasound examination of the
leg.  Unfortunately the ER physician was busy with something more
serious at the time they sent me home so I was sent home with a
diagnosis of "lower extremity pain"  (as if I didn't know that) and an
Rx for Percocet.   I was also told that if I had difficulty breathing
(in other words, they missed the clot) or if I had fever (I have a
broken blister on the foot--they thought there might be an outside
chance that the pain was caused by cellulitis) that I was to come
immediatly back.

At my followup visit with my physician yesterday, he could shed no
light on the situation.  First of all, he didn't have the ultrasould
resuts as the hospital said they could not locate them so soon after.
He said it was probably a strain but might be an infection as I did
have some slight redness.  He prescribed Keflex 500mg 4x/day for that
possibility.

What I forgot to mention was that the ultrasound tech said it looked
suspiciously like a broken cyst in the knee, which had leaked into the
calf.  He said he sees this at least twice a week for people with
suspected blood clots.  Now he is just the tech, not the radiologist
who reviewd the ultrasound.   However, on the internet this morning I
have found that this is known as a "Baker's cyst" and that these
rupture and mimick blood clots.

Should I call my Dr back and mention this (he told me not to follow up
unless the pain worsened or did not get better in the next few weeks.)

If this is indeed a ruptured cyst, it should be on the ultrasound
report, which my Dr should eventually get.  But, as these things go,
he may never look at it unless I return for another visit complaing of
this pain or unless I otherwise bring his attention to it.
