Thanks for your question on Healthcare Magic.
I can understand your concern.
Myeloproliferative disease is a kind of
blood cancer (malignancy involving blood cells).
This can spread to flat bones like ribs,
scapula and also in abdominal organs like spleen and liver.
So in your case, we should definitely rule out spread in ribs and spleen for this pain.
So get done CT scan or PET scan as soon as possible.
For pain relief, you can do following things.
1. Apply alternate ice packs and warm water pad on affected areas.
2. Avoid movements causing pain.
3. Avoid heavyweight lifting and strenuous exercise.
4. Take painkiller like
ibuprofen.
If spread is there in ribs and spleen then you might need
chemotherapy and radiotherapy.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
