Hi @Lumpybumps1
I apologise in advance if you think this post is unhelpful in any way but it is posted in good faith.
I am not a medical person but your post mentions you not feeling well since the birth of your child
I know your GP has got you on a 2week pathway for Lymphoma diagnosis but in the meantime it could be worth looking at your recent traumatic birth.
You say that you haven't felt well since you gave birth 7months ago.
I read your other thread about you haemorrhaging really badly and also contracting a bacterial infection and you were very poorly.
Anyway, there is a condition called Sheehans Syndrome which affects women who have suffered haemorrhaging during childbirth.
It affects the Pituitary Gland in the brain and basically the lack of blood supply causes it to stop working or partially working(Hypopituitarism).
It causes havoc with various hormones Growth Hormone, Thyroid, ACTH(adrenaline and cortisol) and many others.
It can cause all the symptoms you have described and many more but they will not all show up at once.
No 2 patients are alike. Not all hormones will be deficient. It could be e.g.Growth Hormone and Cortisol but the sex hormones may be unaffected.
The first thing that happened was that I caught every illness going, was told after about 6months it could be glandular fever.
I had enlarged lymph nodes in my neck.
Horrendous sore throats that seemed to affect one side
Ear problems
TMJ(I have had over 50 dislocations of my jaw since this whole thing started)
lower back pain that would come out of nowhere
I was unable to stay awake for a full day
Adrenaline seemed to run non stop, I was hypervigilent and jumped at the slightest noise.
As years went by I was diagnosed with CFS/ME(severe fatigue that never went away), Anxiety(my adrenals went into overdrive) and Depression(I slept for long periods).
It would take 15years for me to be diagnosed with Hypopituitarism(mine was caused by a severe head injury).
I would not wish those 15years on my worst enemy. Sorry not trying to be dramatic.
You would need to ask your GP for a referral to a
Pituitary Specialist/Endocrinoligist for specific testing which cannot be done by your GP.
Also the chances of your GP ever having seen a patient with Sheehans is very rare so she may not have come across someone with it.
Here are a couple of links that explain the condition

I hope this helps
