HI, thanks for using healthcare magic
The
tingling and
numbness are likely due to neuropathy which refers to abnormal function of the nerves, there can be different causes but autoimmune diseases such as
rheumatoid arthritis are one of the causes.
Other causes of neuropathy are: (1) low levels of
vitamin b12 and folate
(2)diabetes
(3)side effect of medication
(4)thyroid disease
(5)liver or kidney disease
(6)infection such as shingles
(7)other autoimmune diseases
(8)neurological conditions such as ms or stroke
(9)trauma to the nerves eg arthritis of the neck or shoulders can affect the nerves in the area
It maybe best to see your
rheumatologist who manages your RA first to see if it is related to this condition.
If this is not the case, then the other causes mentioned would need to be ruled out by blood tests and imaging
I hope this helps
