Hello Waspereeze,

To try to understand what is going on, more infos are needed.

Did you notice these strange sensation straight after the bodypump session? Is it localised just to the left shoulder or does it goes by time to time to the right too? Are these sensation constantly there regardless what you do? Is there anything that make it better or worse? ice/cold or hot shower/bath? Do they radiate anywhere else? are there any daily pattern? is it worse/better in the morning? do you have any other associated symptoms? short of breathness when you wouldn't expect or palpitation? Have you had previous episodes or this is the first time you had it?

A part from that problem, how would you describe your health? do you smoke? and if you do how many cigarettes?

Considering that you are in London, check out if you can have a consultation in any osteopathic teaching clinic (BSO or BCOM for example) surely you won't have to wait 6 months!

Keep us informed

all the best

Emanuele
