I had Inguinal Hernia surgery 30 days ago and last night ate lobster, felt an itch on the left side of scrotum, had some oozing and redness. The itch has stopped however the redness remains, there is no pain, nor itch or discomfort. PS
Hi, It may be contact allergic dermatitis on the left side of scrotum. Consult the dermatologist for the perfect diagnosis and proper treatment. Take antihistamines like Cetirizine daily and apply combined cream of steroid and antibiotic. If you needed, take oral steroid in tapering dose. Avoid contact with suspected allergens. Avoid soap bath. Take Site bath in Detail mixed water.  Hope I have answered your query. Let me know if I can assist you further.
