I have psoriatic arthritis .. my joints give up before my muscles do and it's painful and frustrating since I have the strength to go very heavy .. Deca completely masked the pain for me, but hey it's going to come back worse but it surely masks 99% of it .. EQ does mask the pain too (never tried it, only read about it) .. did you check your estrogen like "Chemically enhanced" said? if crashed it causes joint pains .. when I crashed mine before combined with my arthritis it was hell on earth ..
"Etoricoxib" may help, it's a COX-2 inhibitor .. take it at 120mg one tablet a day with food for a week and see how it goes .. for me when my fingers start to swell a bit and my joint start aching too much, it removes most of the pain after a week or so ..
you might wanna visit a doctor if it's not estrogen related and it persists .. mine told me I have to be on Methotrexate .. so I said fuck it .. and I deal with it chemically and with my diet too .. but that doesn't mean you shouldn't go and check it out ..
