Hello, , I am sorry to hear that you are dealing with a lump in the middle of your stomach. We are not doctors and can not give medical advice (or diagnosis) over the internet, so I really encourage you to reach out to your doctor if you haven't already. It might be helpful for them to be able to see the lump and examine it themselves. We always encourage that with any new or worsening symptom one checks in with their doctor as the doctor can best determine what is causing the symptom. I'm sorry that I can not be more specifically helpful, but hopefully, as you wait to hear from your doctor, some of our community members here can share if they've had any similar experiences. Please, if you're comfortable, keep us updated on how you're doing and what you find out from the doctor. Wishing you a gentle day. -- Warmly, Christine (Team Member)
