Hi thanks for your query and welcome to lybrate. I am dr akshay from fortis hospital, new delhi. I will try to help you from an orthopaedic point of view, it seems that you have pain
at thumb base since 3 months but you have mentioned no swelling
there. I will advise you: 1) to wear a thumb spica splint for 3 weeks 2) ice packs for local application 3) a short course of anti-inflammatory medication 4) physical therapy if it does not improve, then kindly let me know and we might have to get some investigations done for you. Do not hesitate to contact me if you need any further assistance.
