Found this massage centre in Fitness First near Brighton Station on the internet simply by typing "massage place near me". The slots available are easy to book, they are really flexible, on cancellation, (though out of respect for self employed people one wouldn't want to do that anyway).
Harbinder my masseuse was excellent, once I'd appraised him of the problems.
Plus they're cheaper than other places.
Will be returning...
My subscapularis muscle (the armpit muscle) felt tender. I can feel that it is no longer as tender as it was before after Haminder gently reduced the pain with his massage techniques✅✅✅
