Thank you for the information.
I am sorry to hear about your symptoms.
Based on your description, you have lower backache along with pins and needle sensation off and on. Since you have it for 10 days only, I am not strongly suspecting it as a arthritis specially at your age, but musculoskeletal pain is quite possible. Good thing is that most people with muculoskeletal pain recover with conservative measures such as rest, ice/heating pad, mild stretching exercise, physiotherapy
, and pain meds. OTC meds are generally good for these purpose, but stronger pain meds can be prescribed in a situation when regular pain meds are not helpful. It is also important to note that, lower backache can be also due to nerve compression/irritation, in that case also these conservative measures are helpful. For nerve related pain meds like lyrica, neurontin can be also considered for better pain control.
As far as pins and needles are concerned, it can be associated with wide number of causes such as nerve damage, diabetes, exposure to toxins, chronic alcohol use, vit B12 deficiency etc. It can also be associated with thyroid
problem, decrease blood supply to the area or nerve root compression. I would certainly recommend you to visit your doctor for proper evaluation. You should consider blood test, urine test, x ray lower spine/MRI, thyroid test to find out the cause of backache and those sensation.
One more important thing, if you get these sensation as an attack to only one side of your body, that persist for a short period and disappear, then neurogenic/brain related problem also needs to be ruled out. Thus, I see a very strong need for neurologist evaluation.
Please let me know if you have any other question for me.
