Thanks so much for your kind thoughts everyone.
Mrs.D,
Because most of the blood and urine analysis consistently came back within the normal reference ranges, the doctors are 95% sure that the high platelet count is a reactive one; also termed "Secondary Thrombocytosis"

RF, ANA, Crp, Liver enzymes, RBC, Hct, B12, Folate, Ferritin, TSH/T4 & T3, urate, plus a bunch of others that I can't remember were all either negative or pretty much in the middle of the reference ranges.
WBC & Neutrophils are slightly out of range on the high side, MCHC is out on the low side, and platelets came in at 804. The comparative reference range for platelets is 160-380 x 10(9)/L.
The cardiologist thought that the clot probably came from a deep vein thrombosis and might not even be related to the high platelet count. Apparently secondary throbocytosis doesn't increase the likelihood of clot formation.
That sounds reasonable because I haven't been able to walk about, or work out on the cross country ski machine as much as I normally do because the hand and wrist joints are too sore to use for support with a cane or to hang on to the ski machine with.
Crumb...I can't even operate a manual can opener or open a bottle of juice because the twisting motion is too painful...if and when I can keep a grip on those things, that is.
I need support to walk because the ankles are also inflamed and painful now, along with the left hip and left knee. Crutches have been working the best because I can put some of the body's weight on the arm pits, but that's only good on level ground or in the house.
Thus, I've been sitting more than normal. Even though I have been doing stretches and lots of contractions for the legs, it obviously isn't enough.
I'm just going to have to get past the pain in the joints and get back to walking and using the ski machine.
I also have a mini trampoline, so I'm going to give that a try as well to see if the lower joints will take it. Even some light bouncing will get the blood flowing better in the pegs. I'd go to the local pool to walk and exercise in the water, as I've done in the past, but the risk of slipping on the deck or catching a bug at this point is too great.
I'm sure that I'll figure something out that doesn't get the joints too upset

With love, Erika
