Arms falling asleep since I packed on muscle

I've been on TRT since Aug. Last 2 months I've really grown my shoulders and chest. I'm around 16% body fat.

I'm finding I wake up with arms that are dead or tingling. I'm ok when I travel and sleep on a cott on my back but at home I side sleep and wake up frequently uncomfortable due to shoulders or arms falling asleep.

I feel like I remember this being common... Any ideas?
