Knee Bruises Afer Standing For Long Time, Crunching Sounds When Knees Bent.
Thanks for posting your query.
At her age, the symptoms she having are suggestive of inflammatory joint problem which gets aggravated by an abnormal posture. For proper diagnosis, some of the blood tests are advisable like-
1. Serum calcium levels.
2. Serum Uric acid levels.
3. RA factor
4. ESR (Erythrocyte sedimentation rate)and CRP (C-Reactive protein).
5. Serum Creatinine
6. X-ray of affected joints.
She needs a thorough clinical examination followed by investigations under the guidance of an Orthopedician.
Till then, for symptomatic relief, she can take over the counter analgesics, do hot fomentation and apply local analgesic gel on the affected areas.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
