been tested for lyme, ra, this pain is in all joints . thank you, for your comment
flu like symptoms can initiate when a systemic problem is occuring.
you should be evaluated for underlying diseases that can cause joint pain such as lyme disease. bacteria invasion and viral invasion can spread to the joints which can cause joint pain also. i suggest getting blood work for the following: ana, hla B-27, HbA1C, RA, lyme titer, rpr, esr, crp. these markers will help let us know if you have a virus, systemic disease, diabetes, etc. i suggest going to have this examined to make sure you don't have anything serious causing the pain. if all is normal, i suggest wearing supportive shoes like a sneaker and purchase a new pair if older than 1 year.
