There is nothing specific in Medical Science, There are criterion and average duration for the procedures but things vary from case to case. In case of Implants and rods patient is always recommended to visit the Doctor at specific intervals as advised and with time the doctor decides to give patient the flexibility in movements and exercises. Generally when things start improving and we start feeling better and gradually we start discontinuing the visits to the doctor and start feeling healthy with everything normal.
In your case also it is more of negligence, you shall have consulted your doctor before starting any kind of exercise. The exact situation could be assessed by your doctor only, so do it at the priority and stop all the exercises involving that joint. The problem could be a sprain
, muscle injury
or muscular spasm. In such cases you need to take analgesics, anti-inflammatory medicines and application of ointments
, so please do not take them on your own and have them strictly under the supervision of a qualified doctor.
As far as the role of rod is concerned, it is used there to strengthen the bone or replace the bone, so again it could be decided only on the basis of Clinical examination and radio-logical investigations like X-ray, CT-Scan etc. So the best thing you can do now is contact your Orthopedics at the earliest.
Wish you a speedy recovery to health.
