Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, possibility of nerve related pain (mostly
sciatica) is more.
No need to worry for bladder infection in the past as this can not cause such pain.
In my opinion, you should consult orthopedic doctor and get done clinical examination and
x ray of LS (lumbosacral) spine to rule out nerve compression.
You will need combination of
pregabalin and methycobalamime.
Physiotherapy in the form of
ultrasound, wax and warm water pad application are effective.
Avoid heavyweight lifting and strenuous exercise. Avoid Sudden jerky movements.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
