I am 6 weeks post op and I experience random INTENSE itching. Is this normal? How can I make it tolerable?

Occasionally severe itching can accompany healing after body contouring. If the customary antihistamines don't work sometimes a drug like Neurontin might be indicated. This is something you should discuss with your surgeon.

Itching after liposuction is caused by inflammation (dermatitis secondary to some mechanical irritant - garment, heat or medication reaction- antibiotics, pain meds, skin glue); reinnervation as the sensory nerves settle after the liposuction.  Antihistamines and moisturizing agents are effective.  Removing,  the mechanical irritant also helps.

Thank you for sharing your question and photographs and I am sorry to hear of your itching issues.  Based on the location of your scratches this is like related to irritation and dryness of the skin from either adhesive, gauze, sterilizing solution, compression garments, etc.  I would first recommend cleansing your skin with a gentle soap to remove any remaining irritant and then apply a thick emollient like Aquaphor.  Take a higher dose of Benadryl and discuss either a topical steroid cream or oral steroid pack with your surgeon as they know the full details of your procedure and can offer you the best treatment recommendation.  Best wishes.
