Can lymph nodes stay swollen for 7 months after mono infection. lymph nodes are bilateral in post. cervical area 1.3 cm or less. i touch them everyday?

Yes, not abnormal: Once inflamed and enlarged, sometimes lymph nodes never return to previous normal size. If you're otherwise well, it doesn't mean anything if you can still feel them. Anyway, repeated touching -- especially if you poke hard to find them, rub them, etc -- can cause further inflammation, keeping them large. I suggest you vow to keep your hands off for the next month. You may then find they're gone.
