Aching muscles is this safe?

P

I’m 21 weeks and before becoming pregnant I used this every night, ive always had a bad shoulder and it’s the only thing that helps me. I’ve not used anything on my shoulder during pregnancy because most aren’t safe at all but is this one safe? It doesn’t say anything about not being able to use it but that doesnt mean it’s safe to use. If it’s not safe, does anyone know anything that is safe but is also like a cold deep heat instead of the hotness, the cold ones are the only ones that work. I’ll ask the chemist in the morning because the pain is too much but I have some of this and really need to know. It’s 2am now and I’m crying and I’m exhausted. Nothing is helping the pain 😔
