Welcome to HCM.
As you have mentioned you go to gym regularly, i think it might also be due to muscle spasm. It will be better if you use over the counter analgesic
spray/cream it will be helpful.
may resolve on its own or it may require treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen
, naproxen, and indomethacin
. NSAIDS help reduce inflammation and pain.
If the pain is bothering you a lot i advice you to see physician for further help.
Hope I have provided the information you needed.
Wish you good health. Take care.
