Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you are having
nerve compression in sitting position which is causing you pain especially in sitting posture.
You should first try below mentioned non pharmacological measures for pain relief.
1.Avoid heavyweight lifting and strenuous exercise.
2. Avoid sudden jerky movements like bending, side movements etc.
3. Apply warm water pad on affected areas.
4. Avoid bad postures in sleep.
You will mostly improve with all these in 1-2 weeks, if not improving then consult orthopedic doctor and get done
x ray of lumber spine to rule out compression.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
