Fatigue and pain

I had a VATS lobectomy of lower lobe in rt lung in 3/2017. Then chemo consisting of cisplatin and navelbine for 4 months which hammered my body and required transfusion twice. I finished that in Sept. 2018. I have had clear scans every 6 mos, and the last one in Dec. 2020 was also clean. Based on that I am now to go to yearly scans. So this is encouraging, right? I am grateful that it appears so far I don't have a recurrence. However, I do have extreme fatigue. I can easily nap for 2 hrs. every day. I experience pain in feet, lower back, shoulders and in general it is exhausting. I don't know if this pain and fatigue is from chemo or from arthritis, which I have badly in knees. I do have neuropathy in feet. Numbness. It is depressing to go through surgery and treatment only to come out of it all with these issues. Doctor has suggested Lyrica or tramadol. I have strange reactions to drugs, lots of allergies.
