Lymphocytosis & palpitations since May.

Hi, I suffered from bad acid reflux issue in May 2020 followed by sudden onset of palpitations and mild fever (99-99.8). Gradually, slight swelling & pain appeared in my neck and ear area as well. Lymphocytosis was found in my blood test with mildly elevated ESR. The doctor suspected bacterial infection and kept me on 1 week antibiotics with antacid. I experienced a seizure/ migraine aura during that period. In Jun-Aug 2020, I suffered from bad typhoid for 3 months & it turned negative in August 2020. I never got rid of symptoms like palpitations, ear pulsations,etc. My echo/ ecg was normal in September and lymphocytosis was seen again. Current symptoms are severe palpitations, weakness, on/ off mild fever, ear pulsating, low bp, dull ache under breast bones, pointed pain in right side of upper back, crackling in joints, stomach issues & pink horizontal bands on all my fingers. Attaching pics with recent report suggesting lymphocytosis. Please help & suggest possible reasons. Thanks
