Tender areas on abdomen and feeling of clenched tummy muscles

Have 2sore points on abdomen a year since TT with muscle tightening & Lipo Also a feeling tummy muscles are permanently clenched as if I am unconsciously holding them in 24/7. Physio says I may be not resting them habitually or unconsciously holding them in so fatigue causes pain what might cause Me to hold them in eg muscle spasm after surgery.? Would a muscle relaxant help ? My surgeon suggested nerve pain as a possibility and has no explanation what the 2 sore points are. Thank you.
