I have had a high platelet count since i was pregnant 3 years ago. jak2 neg, neg spleen ultrasound , no symptoms. have joint pain and recent swelling ?

Joint symptoms: Joint pain and swelling certainly raise the suspicion of rheumatoid arthritis or collagen disease like lupus in a young woman. Thrombocytosis(high platelet count) is usually the opposite of what is seen in connective tissue disease, but can lead to excessively easy blood clotting and should be followed by a hematologist while a rheumatologist can evaluate your arthritic symptoms.
