Thanks for your question on HCM. In my opinion you are having muscular injury due to tight hugging and squeezing by your boyfriend. Do try to follow these steps for better symptomatic relief in muscular pain. 1. Avoid heavy weight lifting and strenuous exercise. 2. Avoid bad postures in sleep. 3. Take good painkiller and muscle relaxant. 4. Apply warm water pad on affected site. If not improving in 2-3 days than consult pulmonologist to rule out asthma worsening as you have asthma.
