Masturbating with anal fissure

Can’t really find anything definitive on this but shouldn’t you avoid masturbating if you have an anal fissure? I feel like it would be an awful idea to do, as you’re tensing everything up down there. Surely that would retear you or make it worse if not healed? Anyone have experience or thoughts one way or another? Once healed how long should you wait? I will NOT be risking it because it’s not worth it even a little bit lmao I haven’t since I got my fissure maybe a month or two ago to be safe
