I've had some bicep pain here and there, though it wasn't my most common or severe complaint. Sounds like nerve compression to me.

Hi Akash, I sleep on my back with a Sofflex overlay on my mattress made by Roho. I use a couple of pillows under my knees underneath the sofflex to stop me from rolling over. It works well for me, sofflex resolves pressure care and circulation issues related to being in one position too long. I also have nerve damage down my back (long thoracic nerve) caused by the TOS and cannot sleep on my back without the sofflex due to nerve pain. I find it well worth the cost. Not sure how much in USA. An occupational therapist helped me to find this solution.
good luck
