I have been having shoulder pain/weakness going on 5 months now.

My TRT regimen is currently 100mg Test C /wk,100mg Nandrolone for joint and shoulder pain .5mg Anastrozole/wk
I recently learned that my shoulder weakness and pain is coming from a pinched nerve in my neck.
For the past 2 months i have been taking Antiinflammatories (NSAIDS) for the pain.
I am wondering if there are any known interactions between these drugs.
I have been having dizzy spells when getting up from a sitting position for a few weeks now,this is rather unusual for me
something is out of whack for sure.
