Welcome to HCM
You are takig medicines which belongs to analgesic
and antinflamatory group and steroid (Prednesolone),they must be taken under strict medical supervision and not indiscriminately,if they are prescribed to you. But it is not clear what for they are given?
You have arthritis
in knee or hip? or pain radiating from back which could be nerve pain
and may not respond well to analgesics.
Ricam is cetrizine which is anti allergy medicine will not decrease pain at all.
Long term use of analgesic can damage kidneys.Even steroid have many side effects.
please consult a Orthopaedic Surgeon
and get a MRI Spine and some blood test
to know exactly where is the pathology ,treat ment can be planned after diagnosis.
Good Luck to you
