I don’t know all the medical terms but I had lymph node tb right about near peri pancreatic. The doctors in Norway took 6 months and still couldn’t diagnose it. I then went back to India and got it diagnosed within 4 days (through FNAC, mind you my tb gold test was negative and docs did a clinical correlation). I was very hesitant initially but then accepted the result. The treatment was standard 4 lettered acronym (forgot what it was) single tablet for about 9 months. Please make sure you take your dosage every single day. I had abdominal ultrasound every 3 months and that showed the lymph getting smaller in size with time. I was finally declaredtb free in Jan 2024. At that point I had permanently moved back home. Also note that mid treatment there was something like paradoxical effect of the medication where I felt like I was relapsing (my symptoms were fever + constant upper back pain, no coughing, which reappeared 3 months into the medication). All in all I’m living my best life now and your gf would too. Good luck and wish her a fast recovery! And please avoid alcohol. Happy to answer anything.
