Itchy, burning skin all over for about 20 months. What is probability this is coming from Hodgkin's or NHL?

I have had itchy, burning skin for about 20 months. My skin will turn red, but I do not have a rash of any sort. There are times when the symptoms will go away completely, but then they will return. I do not have any other symptoms like fever, night sweating, or weight loss. I have had an MRI of brain, chest x-ray, ct scan of chest and abdomen, and multiple blood tests. All scans have come back normal. The results of my most recent are: SODIUM 140 MMOL/L Range 135-145 POTASSIUM 4.5 MMOL/L Range 3.5-5.0 CHLORIDE 103 MMOL/L Range 98-107 CO2 30 MMOL/L Range 22-30 UREA NITROGEN 11 MG/DL Range 7-21 CREATININE 0.95 MG/DL Range 0.70-1.30 ANION GAP 7 MMOL/L Range 9-15 BUN/CREAT RATIO 12 UNDEFINED GLUCOSE,RANDOM 81 MG/DL Range 65-179 CALCIUM 9.3 MG/DL Range 8.5-10.2 MAGNESIUM 2.1 MG/DL Range 1.6-2.2 PHOSPHORUs 3.5 MG/DL Range 2.4-4.5 URIC ACID 6.3 MG/DL Range 4.0-9.0 PROTEIN,TOTAL 7.0 G/DL Range 6.6-8.0 ALBUMIN 4.6 G/DL Range 3.5-5.0 BILIRUBIN,TOTAL 0.3 MG/DL Range 0.0-1.2 AST 31 U/L Range 19-55 ALT 41 U/L Range 19-72 ALKALINE PHOSPHA 100 U/L Range 38-126 GGT 46 U/L Range 13-68 LD 509 U/L Range 338-610 WBC 6.9 Range 4.5-11.0 RBC 4.60 Range 4.50-5.90 HGB 14.4 Range 13.5-17.5 HCT 41.2 % Range 41.0-53.0 MCV 89 Range 80-100 MCH 31 Range 26-34 MCHC 35 Range 31-37 RDW 12.6 % Range 12.0-15.0 MPV 8.5 Range 7.0-10.0 PLATELET COUNT 303 Range 150-440 ABSOLUTE NEUTS 3.9 Range 2.0-7.5 ABSOLUTE LYMPHS 2.1 Range 1.5-5.0 ABSOLUTE MONOS 0.4 Range 0.2-0.8 ABSOLUTE EOS 0.2 Range 0.0-0.4 ABSOLUTE BASOS 0.0 Range 0.0-0.1 LUC 2 % Range 0-4 What is the possibility that my itchy burning skin symptom could be coming from Hodgkin's or NHL?
