The tightness and tingles will be all your re-connective tissue healing. Definitely go see a a therapist to help with massage along the scar site. I felt pulling and like a zap from time to time. I have been doing exercise, gentle physio workout and seeing a physio and a lymphodema therapist to help all the inflammation and swelling from the surgery. I had a nipple sparring bilateral mastectomy with immediate implants 21st Feb. Previous diagnosis was 2011 i had chemo, lumpectomy, more surgery to remove more lymph nodes (plus ovaries and tubes - cancer was hormone positive) then i had radiation. So i figured no more chemo wasn't doing that again. Thru my past journey I found i had many connections to post op solutions for healing understanding nutrition, naturopathy, meditation and yin yoga and various styles of body work therapy like physio. All the best.
