Hello! Thank you for being wit hus on HCM! I understand your concern, and would like to explain that for pain relief you need to try any anti-inflammatory medications, like naproxen, ketoprofen, etc I woud recommend a careful physical medical examination coupled with eventual chest X ray study to rule in/out the first diagnosis of Pleuresy, and to differentiate wit hother possible etiological causes, as it may be shingles:Herpes Zoster (cutaneous rash is suggestive of such a disorder), etc. Some additional lab tests may be necessary, like complete blood count, PCR, etc. Hope to have been helpful to you! Greetings! Dr. Iliri
