Thanks for the query.
As you are not anemia
, menstrual cycle may not be related to your problem.
You once consult orthopedician and get examined to find out the possible cause for your problem.
You may need rheumatoid factor
estimation and thyroid
profile to rule out these abnormalities.
If nothing is found in these investigations, you may need neurologist
opinion and psychological councilling.
