12 months of deep thigh pain at night after NHL - should I be worried?

[APaleHorse]

For the last 12 months I've had significant pain running down both thighs at night while sleeping. Often it is severe and I cannot sleep that much. Some nights it extends down my shins and in to my ankles. It's noticeable during the day but is only mild.
The thing is, I'm a Non-Hodgkins Lymphona (4B) survivor - I went in to remission at the end of 2018 after 6 BEACOPP cycles.
My doctor isn't taking the thigh pain seriously as my blood counts are normal and she thinks it's nerve damage from chemo.
Is she probably correct? I'm worried about further cancer. Has anyone else experienced anything like this.
Any help is very much appreciated, thank you.

You sure have been through a lot!  I'm so happy you are a survivor.  I'm sure everything has the ability to make you very worried.  It's a nightmare and a beautiful dream to survive cancer, I'm sure.  But you did!  And your oncologist is really in a position to know if you need worry or not. That they aren't worried is a very good sign.  They treat many patients similar to yourself and know warning signs.  They know too that some do get the nerve pain she says this is.  You've had marker tests?  I'm sure they are following you closely for recurrence.  Neuropathy is common after chemo.  The tests they usually order for peripheral neuropathy are :
    electromyography, nerve conduction studies, and quantitative sensory tests to further examine peripheral nerve function
    laboratory tests to look for metabolic disturbances and nutritional deficiencies
    imaging tests to look for other possible causes of nerve damage

Many cancer centers have integrative medicine specialists to work on treating this.  

What does your doctor recommend for your next step?
