I am a senior & need help.

Subject Find source of joint pain with inflammation.

Comments My Symptoms, Body Joint pain, left hand
stiffness & pain, & lack of energy,
C- reactive protein tests of 32 /62/ 45.
Rheumatoid test ((9/7) negative.

For past 6 +-month I have experienced a series
of medical issues.
I have seen an orthopedic Dr. & my personal Dr,
(internist), who not been able to identify cause
of my problem.

History Up until 2020 I was healthy , went to Y
.exercised, swam 30 lap a day. In good shape.
When covid started , quit going to Y
& sat at home avoiding personal contacts.
Experienced decline of condition.
At the end of 2021, started having problems
with right wrist pain.
No other pain. Went to see orthopedic Dr.
3/21/22 who started me
on 4mg methlprodnisolone tablet therapy pack.
Took xrays, also ordered MRI, & emg/ncs nerve
tests. Later on 6/9/22 he injected a steroid into
my right wrist.

Since that time, I have experienced joint pains
which seem to have worked its way from my
right hand/wrist , across body into left
hand & rest of body. My joints in elbows,
shoulders, left hand & left wrist began to give
me pain. Also pain in legs/calf's. Problems
sleeping with pain. Whenever I moved the pain
woke me. Also frequent night urination.

Stopped with orthopaedic dr in Sept .went to
see personal dr, (internal med) & he tested
me for :
C-reactive protein, 3 times (first 32 / 2nd62/
3rd45)
rheumatoid factor negative
ana negative
cyclic citrul peptide negative
basic metabolic panel
My Dr. prescribed a repeat of
methlprodnisolone tablet therapy
pack. Same results. Temporary improvement.
After few days improvement/benefits
disappear. Pain again. Not sure, my Dr.
knows what to do.

Required Need diagnosis of cause of joint pain/wrist
pain/leg pain, c reactive protein tests, high
immunization/inflammation problems. Is this
an auto immune problem?
