I Felt Itching And Temperature Variations And Went For Blood

I felt itching and temperature variations and went for blood test and found my Haemoglobin count is above 17. I went AIIMS and they asked me for polycythemia vera test, for JAK2 mutation. That result came negative. Surprisingly that test was conducted on few JAK2 variations and did not tell about exon 12 variations. I still face same burning, pricking, itching problem, and sometimes my head feels like throbbing. I feel sudden waves of weakness and heat. I am attaching my blood and JAK2 test reports, please guide me. I had swollen lymph nodes problem too and sometimes had blurred vision, although that's rare.
