I am Dr. Arun and will be helping you today.
I am sorry that your question was unanswered for long.
Your investigations are normal and do not indicate any specific diagnosis for the knee pain. You may need a x-ray and MRI to ascertain the cause of pain in knee. You may also need blood work for autoimmune panel and gout. Following measures would be helpful in the knee pain, meanwhile;
1) Knee care in the activities of daily living. Few simple self-care measures can be remarkably effective in ending pain cycle.
a) Avoid prolonged standing or walking or sitting with joint in a single position.
b) whenever you sit, keep the knee stretched and fold them intermittently.
c) Squatting, sitting cross legged should not be done.
d) Avoid climbing stairs.
e) Avoid sitting legs unsupported or hanging.
f) Reduce weight if over weight/obese.
2) Rest: Taking a break from your normal activities reduces repetitive strain on your knee, gives the time to heal and helps prevent further damage.
3) Anti-inflammatory medications
4) Physical therapy; the goal of physical therapy is to strengthen the muscles around your knee and help you regain knee stability. Ideal is supervised physical therapy. Stretching exercises are also part of the physical therapy regime.
5) Orthotics and bracing.
The most common causes of anemia are;
1) iron deficiency (with or without blood loss),
2) chronic disease/inflammation
3) chronic kidney disease
4) deficiencies of folate or vitamin B-12,
5) diseases of the bone marrow
6) hypothyroidism, hypersplenism, and hemolytic anemia
So investigations entail (if not already done);
1) Complete blood count (CBC)
2) Peripheral blood film
3) Vitamin B-12
5) Reticulocyte count
7) Thyroid-stimulating hormone
8) Serum creatinine and estimated glomerular filtration rate
9) Serum ferritin
10) Serum iron
11) Total iron-binding capacity
So these investigations need to be done for the exact assessment and long term management.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
