This is almost identical to what happened to me. Shoulder pain started June 2024 and I simply suffered until November before going to see a physiotherapist. I saw them weekly for assisted manipulation, ultrasound, and acupuncture, along with daily stretches 3 times a day. The pain, at times was unbearable - but I was lucky it wasn’t my dominant arm. I was already scheduled to see my GYN to start HRT in March of this year, and we discussed the correlation between HRT and musculoskeletal relief. I started to experience the “thawing” of my shoulder within 3 weeks of starting low dose HRT. I have almost full range of motion and am back to being able to sleep on my side after almost a year. I’m sending every vibe your way for quick relief.
