a lot of pain and what not.. ideas?

a few years ago i (17F) started getting more tired, no matter how much sleep i got, and then also pains in my ankles which over time spread to my knees and back. this year, after a wedding , i genuinely couldn’t get out of bed because of how much pain i was in. i was then diagnosed with Multilevel cervical disc desiccation as well as being tested for keratoconus and now referred to neurology. here’s lists of symptoms.

loss of grip / strength in my hands happening for a year or so headaches neck / back pain, makes it hard to stand joint pain in my ankles / toes / knees / hips/ shoulders / elbows jolting pain in forearm / elbow and legs muscle weakness all over pains in ribs / stomach constant tiredness / fatigue random pains in legs pins and needles in hands/ legs dizziness/ confusion memory loss breathing difficulty shakiness random involuntary movements in legs or fingers hallucinations small phases of blocked vision.

i have my theories but any other thoughts would be appreciated,i do smoke but not very often - same with drinking. i dont take any constant medication , and paracetamol doesnt work for me at all , the only pain killer ive found to help is ibuprofen- which only really takes the edge off.
