It sounds like you haven’t been given a diagnosis. Do the following
1. Blood tests- ESR,
CRP, HLA-B27, C3, C4, ANA, Anti-dsDNA, Anti-Sm antibodies and
Vitamin D levels
2. MRI whole spine and sacro-iliac joints for any evidence of ankylosing spondylitis
3. Short course of anti-inflammatory medication like Ibuprofen
All the best.
