Hi Dear !! Thanks for your query to HCM . Read and reviewed your query and health concerns. You seems to suffer from-Fibromyalgia with Allergic attacks with ?Costo-Chondritis. IN presence of Allergic attacks and shots for their recovery,Steroids for Costo-chondritis would not be a good option to try. INstead I would suggest to rule out the Fibromyalgia and give trial for Tab Montelucast(Singulair) with Loratadine Tab PPI with -Ibufrofen 400 mg- x 10 days would give the lead,which way to go. Giving trial to accompanied-Vit D / Calcium / Magnesium supplements with sunbath -for 1 mth considering your age- need to be tried. This is because,when the immune system is hypersensitive and compromised ,which could be due to lack of Calcium and Vit D defficiency,destroying it more with Steroids would only stress the bones by being more osteoporotic -leading to more pains at ? Costo-chondritis. If no relief-Check X-rays to confirm Costo-Chondritis-and local steroid shots would be suggested, in such a situation. Other causes of accompanied illnesses causing such a symptom complex need to be ruled out. Hope this would help you to plan further care of this complex illness of yours.
