How do I know if I have developed seroma ?
It is unlikely to have developed a seroma 40 weeks after a TT. Lumpiness which is not seroma may exist for 1 year or more. But I would recommend returning to your PS for follow-up. Good luck!
What procedure did you have done?? It is possible to get a late seroma after a tummytuck but it is unusual. I would recommend going back to your PS and maybe he/she can get an ultrasound to look for a fluid collection. Best regards!
