I am 4 months post L4/L5 discectomy. Doing PT once a week and recently started Pilates as recommended by my PT. She also said I was ok to go gym again but to use machines for weight lifting exercises and light weights. Also do cycling, swimming and cross trainer. I went gym yesterday morning and session went well - didn't have any pain however latest night the pain in my right calf appeared - it's more of a burning sensation rather than shooting pain. I'm going to rest all week and see PT next week if it remains however wondering if any has had similar experiences?
