Hello,
Thank you for your query.
Steroid therapy can cause muscle and
bone pain as it displaces calcium from them.
I recommend taking 500mg of calcium with
vitamin d3 supplements- one in the morning and one at night for a month and then to one a day. This is supplemental to her dietary intake, not a replacement.
If her pain worsens, redness occurs with swelling of the leg, please see her physician right away.
Codeine (in cough syrup) can cause
drowsiness and
dizziness. I recommend reducing the dosage or even stopping the medications after talking to her doctor. If cough is minimal or productive, she doesn't need to suppress it with Codeine.
Steam inhalation can help loosen secretions and keep airway moist.
Hope this helps.
Please let me know if you have any further questions.
Wish you both good health
