hi
thank-you for providing the brief history of you.
As mentioned in the history what I am able to understand that you have 22 months old baby, diastasis rectii, pain in pelvic region,
swollen lymph nodes etc.
I want to ask you a question - was the delivery normal? were you physically active before pregnancy? have you undergone
physical therapy post delivery?
Now , due to the changes in the hormones there will be possibility of the lymph node swelling and also pain and aches. But this are all temporary. Your all tests are negative so you should be happy that nothing major is there.
For first, I want you to start strengthening your pelivc floor muscles, core muscles, spinal muscles, lower limb as a whole which will help you ease of pain and aches.
Also, doing general body conditioning will help improve
metabolism and the swollen lymph nodes will disappear as to understand that with exercise you get good metabolism -> with good metabolism you get good
hormonal balance -> with good hormonal balance your worries are down since no symptoms will be there.
On a small note, in my personal practice I see cases with such issues post pregnancy, and undergoing physcial therapy and body conditioning helps them to reduce alot of symptoms. They later have an active lifestyle.
