Still in pain 5 months after abdominial hernia repair now swelling in groin lymph node tender to touch more painful during period what's going on?

2 issues: 5 months after hernia repair having pain suggests ilioinguinal neuritis. Pain with menses suggests endometriosis unrelated symptoms seek advice.

Not clear: Unclear whether or not this is related to the hernia repair, as the location/size of the hernia is important a well as the technique of repair. Could be endometriosis if it related to menses. See your primary care initially, but don't hesitate to call your hernia surgeon for a follow up visit.
